[Clas12_software] [EXTERNAL] Data and MC processed with AI-assisted tracking

[Daniel Carman]

Folks,

I have compared the new cooking of RG-A fall 2018 inbending data with conventional tracking and AI-assisted
tracking. The results of my study are attached in terms of 4 plots for MM(e’K+) using the skim14 kaon skim
files with the electron in the ECAL.

UL: e’K+(FD) - AI has 19% more events
UR: e’K+(FD)p(FD) - AI has 28% more events
LL: e’K+(FD)p(CD) - AI has 14% more events
LR: e’K+(CD)p(FD) - AI has 18% more events

Here FD implies hadron detection in the Forward Detector and CD implies hadron detection in the Central Detector.
I have used the same run numbers in both studies. I also compared same distributions from the recently cooked files
to the same runs with the original pass-1 cooking for the convention tracking. The number of events for the different
distributions agrees to within a few percent.

Regards,
Daniel

Attached are 3 distributions of the e+e- invariant mass. The old one is what we have from the pass1 processing, using just the 31 runs that have been processed for the AI-assisted tracking test. The new A is from the trainA (reconA) and the new B is from trainB (reconB). So, B has ~25% more J/psi’s than the pass1, A has about 25% less but, of course, with 1 run missing.
