Particle colliders are one such technology that allow us to do this. With the ever increasing luminosity of new particle colliders, such as the High-Luminosity LHC planned to begin operation in 2029, there is demand for detectors capable of taking advantage of this luminosity. The luminosity measures the number of collision events occurring in a given time-frame, and thus it is crucial that detectors operate with a finer and finer temporal resolution to keep up with these advances. This timing data is not only useful for discerning between events, but also for particle track reconstruction, by using spatial data over multiple layers of detectors. Thus, detector development is an active area of research, as these detectors must not only be fast, but also reliable and scalable. A particular type of detector that is of interest is the Gas Electron Multiplier (GEM). Such GEMs already exist in the CMS experiment at the LHC, for muon detection. These sorts of detectors are part of a larger class of detectors known as Micropattern gaseous detectors (MPGDs), named from the fact the each detector contains a micro structure (for example a mesh, or a plate with small holes on the tens of micros scale), that along with the gas inside, allow for very efficient amplification of electronic signals. This has the advantage of making the signals less prone to noise. These detectors also have the advantage of being tolerant to radiation, something of high importance in the particle collider setting. The Gas Detector Development (GDD) lab at CERN designs and tests new prototypes for MPGDs, with the goal of achieving timing resolution on the picosecond scale, while being both robust and scalable. In particular, this project focused on marrying the Micro-Mesh Gaseous Structure (MicroMegas) detector with optical Silicon Photomulitpliers (SiPMs), to investigate whether the fast timing of the Micromegas can be corroborated with the superior spatial resolution of the SiPMs, to allow for better overall resolution for detecting muons and electrons.\n \n \n CERN EDS\n \n \n SzGeCERN\n Accelerators and Storage Rings\n \n \n SiPMs\n CERN\n \n \n CERN\n \n \n INTNOTE\n \n \n PUBLEP\n \n \n EP\n \n \n CERN.

This report studies the feasibility of applying the data-driven estimation method, the event-mixing technique, to determine that distribution. The event assumes a complete decorrelation between the two leptons, which has seen to be false in most of the control regions. For that reason, we conclude that the method is not robust enough to be applied as a background estimation in BSM searches.\n \n \n CERN EDS\n \n \n SzGeCERN\n Particle Physics - Experiment\n \n \n SUSY\n CERN\n \n \n edge\n CERN\n \n \n CERN\n \n \n INTNOTE\n \n \n PUBLPH\n \n \n \n CMS\n \n \n PH\n \n \n CERN.

In measuring this HFS it will yield a very precise test of CPT-symmetry. For this set-up to work a homogeneous magnetic field is needed in the cavity where the Hyperfine transition of H \u0304 occurs. Due to the stray fields from the CUSP trap, where H \u0304 is produced, additional coils are needed to counter these fields. It is found, using COMSOL simulations, that two coils are suitable for this. Leading to a relative standard deviation of the magnetic field of \u03c3B/B = 1.06%.\n \n \n CERN EDS\n \n \n SzGeCERN\n Particle Physics - Experiment\n \n \n CERN\n \n \n INTNOTE\n \n \n PUBLEP\n \n \n \n ASACUSA AD-3\n \n \n EP\n \n \n CERN.

It is centralized around one interaction point and is designed as a cylindrical multiple-use detector (4\u03c0-detector). The sensitive instruments of the detector measure each emerging particle which is then reconstructed to picture the physical processes. Thus, it is crucial to control effects uncorrelated to the particle collision to fully understand the occurring physics. Those effects not corresponding to the particular collision are called Non-Collision Background(NCB). For deciding what is NCB and what is relevant particle information, triggers are used which search the event substructure based on multiple criteria. These criteria have to be adjusted depending on the expectations and the sources of NCB have to be well studied to find those signal regions excluding them and including relevant data. Amongst other interesting aspects, this procedure opens the weakness, that unexpected new physics that does not fit the signal region is sorted out by those triggers. A possible concept holding such a structure is long-lived supersymmetry. One of the main sources producing NCB is cosmic background radiation. These particles hit the detector potentially from all sides despite its coverage by the underground position. This background can affect several process analyses through its variety of occurrences as well as mimic long-lived processes. This report aims at understanding the Monte Carlo simulation of exactly such cosmic background by investigating the muon chambers dedicated to the trigger response and comparing it with set expectations.

The electrically neutral chemical species produced from such nuclear reactions are then extracted from the target and ionized afterwards in order to be accelerated by an electric field and separated by a magnetic field depending on the mass and the number of protons of those newly produced nuclei. Intensity, which corresponds to a flow of electric charges per unit time, is a physical quantity that fits well the description of such phenomena and is used to characterize these accelerated nuclei that we usually call Radioactive Ion Beams (RIBs). RIBs intensities are measured by pico-amperemeters that communicate directly with LabVIEW, in which we can manipulate the acquired data in order to make some statistics, signal processing, graphs, or write them to files. The aim of this summer project was to implement some instruction stages in such a way as to facilitate the use of the previous current integrator, and also in order to allow the automatic writing of data in a text or excel file and to be able to write useful information such as comments or the name of the user performing the experiment.\n \n \n CERN EDS\n \n \n SzGeCERN\n Particle Physics - Experiment\n \n \n CERN\n \n \n INTNOTE\n \n \n PUBLEP\n \n \n \n I216\n \n \n EP\n \n \n CERN.

More specifically, $\\textbf{cptnHook}$ addresses a current issue that arises from the the extensive use of very time-consuming mathematical functions (such as transcendental functions) that results in them accounting for a big portion of their run-time. It is believed that the problem can be addressed with ad-hoc approximations of mathematical functions, for which a clear overview of the usage of the functions in the program is required. $\\textbf{cptnHook}$ approaches this problem by providing a measurement of the use of mathematical functions in a program by hooking into the machine code and probing the arguments of the functions, without modifying the application's source code.

The running is extracted from a measurement of the differential top quark-antiquark ($t$$\\bar{t}$) production cross section as a function of the invariant mass of the $t$$\\bar{t}$ system, $m$$_{t\\bar{t}}$. The analysis is performed using proton-proton collision data recorded by the CMS detector at the CERN LHC in 2016, corresponding to an integrated luminosity of 35.9 fb$^{\u22121}$ . Candidate $t$$\\bar{t}$ events are selected in the final state with an electron and a muon of opposite charge, and the differential cross section d$\\sigma$$_{t\\bar{t}}$/d$m$$_{t\\bar{t}}$ is determined at the parton level by means of a maximum-likelihood fit to multidifferential final-state distributions. The value of the top quark mass in the modified minimal subtraction ($\\overline{MS}$) renormalization scheme, $m$$_{t}$($\\mu$), is determined as a function of the scale $\\mu$ = $m$$_{t\\bar{t}}$ by comparing the measured d$\\sigma$$_{t\\bar{t}}$/d$m$$_{t\\bar{t}}$ to theoretical predictions at next-to-leading order, and the resulting scale dependence is interpreted as the running of the top quark mass. The observed running is found to be compatible with the one-loop solution of the corresponding renormalization group equation, up to a scale of the order of 1 TeV.\n \n \n Springer\n n this thesis, the first measurement of the running of the top quark mass is presented. This is a fundamental quantum effect that had never been studied before. Any deviation from the expected behaviour can be interpreted as a hint of the presence of physics beyond the Standard Model. All relevant aspects of the analysis are extensively described and documented. This thesis also describes a simultaneous measurement of the inclusive top quark-antiquark production cross section and the top quark mass in the simulation. The measured cross section is also used to precisely determine the values of the top quark mass and the strong coupling constant by comparing to state-of-the-art theoretical predictions. All the theoretical and experimental aspects relevant to the results presented in this thesis are discussed in the initial chapters in a concise but complete way, which makes the material accessible to a wider audience.\n \n \n CERN EDS\n \n \n ILSLINK\n \n \n SzGeCERN\n Detectors and Experimental Techniques\n \n \n CMS\n TOP\n \n \n THESIS\n \n \n CERN\n \n \n PUBLCMS\n \n \n CERN LHC\n CMS\n \n \n Lipka, Ekaterina\n dir.\n INSPIRE-00185340\n CCID-721143\n DESY\n \n \n PH\n \n \n 2254427\n 22128655\n http://cds.cern.ch/record/2742366/files/CERN THESIS 2020 148.pdf\n Fulltext\n \n \n 2254427\n 31881\n http://cds.cern.ch/record/2742366/files/CERN THESIS 2020 148.jpg?subformat=icon-700\n icon-700\n Fulltext\n \n \n 2254427\n 3645\n http://cds.cern.ch/record/2742366/files/CERN THESIS 2020 148.gif?subformat=icon\n icon\n Fulltext\n \n \n 2254427\n 4604\n http://cds.cern.ch/record/2742366/files/CERN THESIS 2020 148.jpg?subformat=icon-180\n icon-180\n Fulltext\n \n \n n\n 202043\n \n \n 14\n \n \n PUBLIC\n \n \n THESIS\n \n", @@ -87,6 +88,7 @@ ], "collections": null, "recid": 2741624, + "creation_date": "2007-04-18 03:22:36", "record": [ { "marcxml": "\n 2741624\n SzGeCERN\n 20201214144617.0\n \n DOI\n RWTH Aachen U.\n 10.18154/RWTH-2020-05782\n \n \n oai:inspirehep.net:1807709\n cerncds:FULLTEXT\n cerncds:THESES\n cerncds:CERN:FULLTEXT\n INIS\n cerncds:CERN\n INSPIRE:HEP\n ForCDS\n \n \n http://old.inspirehep.net/oai2d\n 2020-10-17T07:02:53Z\n marcxml\n oai:inspirehep.net:1807709\n 2020-10-16T14:02:25Z\n \n \n Inspire\n 1807709\n \n \n eng\n \n \n Klappert, Jonas\n RWTH Aachen U.\n \n \n RWTH Aachen U.\n Precision calculations for Higgs physics in the standard model and beyond\n \n \n 2020\n \n \n 149 p\n \n \n presented 14 May 2020\n \n \n PhD\n RWTH Aachen U.\n 2020\n \n \n RWTH Aachen U.\n At least since the discovery of the Higgs boson at the Large Hadron Collider at CERN, the Higgs sector of the Standard Model of particle physics has become one of the central research areas of high energy physics. Deviations between measurement and theoretical prediction within this sector have the potential to become a window on the quantum field theories describing nature. Besides the increasing precision of measurements, high-precision predictions are required to become sensitive on possible deviations. The focus of this work is on precise predictions of observables within the Higgs sector. On the one hand, studies of Higgs mass calculations within the context of the minimal supersymmetric extension of the Standard Model are presented, which include partial three-loop contributions. Different kinds of calculational methods are introduced, which, when combined, yield a reliable prediction of the light CP-even Higgs mass for in principle arbitrary parameter configurations. Utilizing the results of this work, the relative uncertainty of the predicted mass of the light CP-even Higgs can be reduced below the 1% level. Additionally, all corresponding results are implemented in an open-source program, which allows for further studies. Moreover, Higgs production in association with a vector boson at the Large Hadron Collider at CERN is studied. By exploiting a symmetry connecting the final state gauge bosons, a particular observable can be defined, that leads to the cancellation of various sources of uncertainty in both measurement and prediction. For illustration, an experimental analysis for this observable is performed, which demonstrates an increased sensitivity to possible deviations between measurement and prediction, and, in addition, yields to evidence for the production of a Higgs boson associated with a Z boson through gluon fusion. Finally, the recent progress in the calculation of two-loop corrections to Higgs-Z production via gluon fusion including the full top-quark mass dependence are presented. To include these quark-mass effects, novel algebraic methods are developed and provided with an implementation into an open-source program, that can find wide application in the calculation of multi-loop Feynman diagrams.\n \n \n SzGeCERN\n Particle Physics - Phenomenology\n \n \n author\n Higgs mass\n \n \n author\n MSSM\n \n \n author\n interpolation\n \n \n author\n multiloop calculation\n \n \n CERN\n \n \n CERN LHC\n \n \n Harlander, Robert V.\n RWTH Aachen U.\n \n \n Kr\u00e4mer, Michael\n RWTH Aachen U.\n \n \n 2020\n \n \n 2254077\n 1677348\n http://cds.cern.ch/record/2741624/files/Thesis Jonas Klapper.pdf\n Fulltext\n \n \n 14\n \n \n THESIS\n \n", @@ -236,6 +238,7 @@ ], "collections": null, "recid": 2316709, + "creation_date": "2013-07-10 03:31:16", "record": [ { "marcxml": "\n 2316709\n SzGeCERN\n 20190603170930.0\n \n oai:cds.cern.ch:2316709\n cerncds:FULLTEXT\n cerncds:THESES\n cerncds:CERN:FULLTEXT\n INIS\n cerncds:CERN\n \n \n AIDA-2020-THESIS-2018-001\n \n \n eng\n \n \n CERN-THESIS-2018-042\n \n \n Paulitsch, Peter\n Vienna, Tech.

This\nleads to new challenges for experiments such as the Compact Muon Solenoid (CMS),\nwhich is already afflicted by aging effects (radiation damages). Therefore the currently\ninstalled silicon sensors of the track detector (\"Tracker\") have to be replaced, furthermore\nto carry out higher radiation doses (through raised collision rates) and increased\ndata rates. The prototypes of the new sensors are provided by the vendors Infineon and\nHamamatsu. These have to be qualified for application by institutes like the Institute\nof High Energy Physics (HEPHY).\nFor this diploma thesis, I did testbeam measurements on these sensors using protons (64\nto 252MeV) at MedAustron and electrons (5.6 GeV) at Deutsches Elektronen-Synchrotron\n(DESY), analyzed the data and utilized performance and quality evaluation. These\nmethods include IV characteristics, noise contribution, cluster analysis, beam profile\nmeasurement, efficiency and energy measurements. In preparation for the testbeams,\nI tested new trigger scintillators to determine dark rates and efficiency and the strip\nsensor system using a radioactive source and a laser test stand at the HEPHY.\nAt the MedAustron\u2019s first testbeam, high particle rates (up to 10^10/s) exceeded the sensor\nsystem\u2019s processing rate. Occupancy and pile-up effects dominated the signal and\ndistorted measured energy depositions. During the testbeam, the bias voltage supply\nof the strip sensor showed compliance, leading to voltage drops. After changes made\nto the accelerator by MedAustron staff, lower particle rates (10^5/s) were available at\nthe second testbeam. These actions, complemented by optimizations in the setup, lead\nto stable power supply and analysis showed excellent conformity of measured stopping\npower to reference data.\nProspective testbeams require extensive preparations in terms of functionality tests,\nstandardization and simulation in advance to identify design flaws. For achieving better\nenergy resolution in future, well-defined particle rate control by MedAustron is essential,\nas well as high time-resolved monitoring the current consumption of the sensor. If\nthere is a demand for low-energy testbeams, it is essential to analyze the non-linear gain\nbehavior in the upper energy deposition range of the ALiBaVa system. Based on that,\none may eventually extend the analysis software algorithm. Further procedures should\ncover protection against electromagnetic interference. Perhaps it will be possible to find\nan appropriate model to characterize electronic noise contribution to improve SNR.\n \n \n FP7\n 654168\n AIDA-2020\n openAccess\n \n \n CERN Invenio WebSubmit\n GENEU\n 0.1\n \n \n SzGeCERN\n Detectors and Experimental Techniques\n \n \n AIDA-2020\n 2: Innovation and outreach\n WP\n \n \n AIDA-2020\n \n \n AIDA-2020THESIS\n \n \n CERN\n \n \n CERN HL-LHC\n CMS\n \n \n Schwanda, Christoph\n dir.\n Vienna, Tech.
