HLT_Ele27_WP80 selection requirements
Here is the list of cuts used for the inclusive single electron trigger.
From Dmytro Kovalskyi.
First a general comment. We have lots of fakes in the endcaps. The
trigger was optimized seperately for barrel and endcap.
L1 seeds: L1_SingleEG20 OR L1_SingleEG22
- super cluster Et > 27
- cluster shape (EB/EE) < 0.01 / 0.03
- relative ecal isolation (EB/EE) < 0.15 / 0.10
- H/E (EB/EE) < 0.1 / 0.05
- relative hcal isolation (HB/HE) < 0.1 / 0.1
- electron tracks are required to have at least 3 pixel hits and
Chi^2/nDoF<1.5 in the endcap region
- |1/E-1/P| < 0.05
- dEta (EB/EE) < 0.007 / 0.007
- dPhi (EB/EE) < 0.06 / 0.03
- relative tracker isolation (EB/EE) < 0.05 / 0.05

HEPDATA
Here is the link to the HEPDATA repository:

It would be very useful if the data and covariance matrices of
new measurements are posted there after the paper has been published.
For example, you can check the format of the recent ATLAS
inclusive jet publication:
