B-Tagged and non-B-Tagged Samples in the TopView Ntuple

It is possible to access three samples of jets, with respect to their B-Tagging status, in the TopView ntuple. The first sample is B-Tagged jets, the second is jets that are not B-Tagged jet, and the third is all jets (B-Tagged jets plus non-B-Tagged jet).

B-Tagged and non-B-Tagged Samples in the TopView Ntuple

Line: 9 to 9
 

Top View Version 11

Variables for B-Tagged jets are denoted by the prefix TJet_ and variables without a B-Tagged jet are denoted by the prefix PJet_. To obtain a sample of all jets, it is necessary to add TJet_ and and PJet_ variables.
Added:
>
>

Since the TJet_ and PJet_ objects are stored in separate arrays and are combined into a single array to form the B-Tagged + non-B-Tagged sample, it is necessary to order the combined array in pT. Failure to do so was causing the small peaks in η (see figure below) observed when the non-B-Tagged jets always occupied the first positions in the array and were therefore always considered to have the highest pT.
 

Top View Version 12

There is only a PJet_ prefix for variables and the tagging status is given by the flag PJet_BTagged. B-Tagged jets are denoted by PJet_ with PJet_BTagged=TRUE, jets that are not B-Tagged jets are denoted by PJet_ with BTagged=FALSE, and all jets are denoted simply by PJet_ without any requirement on PJet_BTagged.

Plots of Samples with and without B-tagged Jets for the s-channel

Changed:
<
<
The plot on the left shows samples of B-Tagged jets (red lined histogram), non-B-Tagged jets (green lined histogram), and B-Tagged + non-B-Tagged jets (black solid histogram). The B-tagged sample extends only to η=2.5 because tracking restrictions at greater η. Notice that in the non-B-Tagged sample there is a large peak in the region where η is slightly larger than 2.5, which corresonds to the region where jets are no longer included in the B-Tagged sample. In the B-Tagged+non-B-Tagged sample the peak is still visiable in this region, although it is proportionally much smaller than in the non-B-Tagged sample.

The plot on the right shows several η distributions, where each distribution shows the effect of a kinematic cut, for the B-Tagged + non-B-Tagged sample. The small peak in the reagion where η is slightly larger than 2.5 is not affected by the jet cuts and only disappers after requiring an electron (green histogram). This suggests that issues with reconstruction are not compeletely resolved.

The peak is most extreme in the s-channel because of the high ratio of tagged jets to all jets.
>
>
The B-Tagged + non-B-Tagged sample on the left is not ordered in pT and the small peaks seen where η is slightly larger than 2.5 is a result of the non-B-Tagged jets being considered to have the highest pT because they were always placed in the leading positions of the jet array. In the plot on the left the jets in the B-Tagged + non-B-Tagged sample are ordered in pT and no peak is visiable.

B-Tagged and non-B-Tagged Samples in the TopView Ntuple

Line: 12 to 12
 

Top View Version 12

There is only a PJet_ prefix for variables and the tagging status is given by the flag PJet_BTagged. B-Tagged jets are denoted by PJet_ with PJet_BTagged=TRUE, jets that are not B-Tagged jets are denoted by PJet_ with BTagged=FALSE, and all jets are denoted simply by PJet_ without any requirement on PJet_BTagged.

Plots of Samples with and without B-tagged Jets for the s-channel

The plot on the left shows a sample of jets which are B-Tagged. This sample extends only to η=2.5 because tracking restrictions at greater η. The middle plot shows a non-B-Tagged sample of jets. Notice that there is a large peak where η is slightly larger than 2.5, which corresonds to the region where jets are no longer included in the B-Tagged sample. The plot on the right shows the combination of the B-Tagged and non-B-Tagged samples. Notice that a very small peak is still visiable in the region where η is slightly larger that 2.5.

This peak is most extreme in the s-channel because of the high ratio of tagged jets to all jets.

Additional Plots of Samples with and without B-tagged Jets for the s-channel

The plot on the left shows a sample only with non-B-Tagged jets and the plot on the right shows a sample with B-Tagged and non-B-Tagged jets. It can be seen that the peaks are much smaller in the sample with the B-Tagged and non-B-Tagged sample, although they still exits. However, after requiring the presence of an electron (green histogram), the peaks disappear, which suggests that there are issues with reconstruction that are not compeletely resolved.

It is possible to access three categories of jets, with respect to their B-Tagging status, in the Top View ntuple. The first category is B-Tagged jets, the second category is jets that are not B-Tagged jet, and the third category is all jets (jets with a B-Tagged jet plus jets without a B-Tagged jet).

The method in which the jets with and without B-tagging are accessed depends on the version of Top View.

The method in which the jets with and without B-tagging are accessed depends on the version of TopView.
 

Top View Version 11

Variables for B-Tagged jets are denoted by the prefix TJet_ and variables without a B-Tagged jet are denoted by the prefix PJet_. To obtain a sample of all jets, it is necessary to add TJet_ and and PJet_ variables.

Top View Version 12

There is only a PJet_ prefix for variables and the tagging status is given by the flag PJet_BTagged. B-Tagged jets are denoted by PJet_ with PJet_BTagged=TRUE, jets that are not B-Tagged jets are denoted by PJet_ with BTagged=FALSE, and all jets are denoted simply by PJet_ without any requirement on PJet_BTagged.
