New commondata format for ATLAS_1JET_7_TEV_R06

[achiefa]

This PR addresses #2390.

EDIT Since the version with R=0.4 is also available on Hepdata, I'm going to implement it.

Details

Implementation of the double-differential distribution of the single-inclusive jet cross sections in proton-proton collisions measured with the ALTAS detector at $\sqrt{s}=7$ GeV. The double-differential cross sections are given as functions of th e the jet rapidity $y$ and the jet transverse momentum $p_T$. The energy interval covered by the jet momentum goes from $100$ GeV up to $2$.

• N. of bins: 140
• Distribution: $d\sigma / dy dp_T$
• C.o.m. energy: 7 TeV
• Energy range: from 100 GeV to 2 TeV

Comments

This dataset was excluded from the NNPDF4.0 baseline dataset according to the selection criteria employed at the time.

Variants

Other than the nominal version of the JES systematic uncertainties, which is used ad default variant in the present implementation, the dataset comes with two additional versions of the JES components. They are constructed by taking stronger and weaker correlations between the JES components with respect to the nominal uncertainties. Both versions are implemented in the present implementation as variants with names stronger and weaker respectively.

Just a comment:

In addition to the nominal JES uncertainties, the HEPDATA tables provide two other variants that differ in the way the experimental components of JES uncertainties are correlated. These have "stronger" and "weaker" correlation assumptions, respectively, with respect to the nominal configuration. I can generate variants for both, in case they are needed. @enocera

Yes please. These were implemented in the old commondata implementation.

[achiefa]

The implementation in the new commondata format is mostly done. I'll add the FK table names to the metadata file once these are ready.

R = 0.6

I have compute the chi2's for the three variants (nominal, weaker, and stronger) using the APPLGrids imported from PloughShare. The table below shows the values of the chi2's.

	Nominal	Weaker	Stronger
Exp.	2.978	2.979	2.915
Exp. + th.	2.361	2.321	2.350
Exp. + th. + pdf	2.226	2.195	2.183

See below for the bin-by-bin data-theory comparisons:

Nominal

Weaker

Stronger

R = 0.4

	Nominal	Weaker	Stronger
Exp.	2.712	2.656	2.744
Exp. + th.	2.362	2.278	2.368
Exp. + th. + pdf	2.211	2.119	2.192

Move things to a single folder

ATLAS_1JET_7TEV

Two observables:
ATLAS_1JET_7TEV_PTY-R06
ATLAS_1JET_7TEV_PTY-R04

(if you can please remove also the sqrts from the filter.py)

[achiefa]

I merged the two radiuses into one dataset. This is good to go @scarlehoff
