This is a good news, the signal is reproducible by at least two people. Now we need to get something similar with FT.

These do look great Will. I have managed to recreate them using very similar cuts and running over all the skim14 data (Pass1), analysing directly from the hipo files. It seems where I was skimming the files, saving as a TTree and then reading it, I had some sort of coding issue, I am investigating what this is now.

Indeed this looks great!!

Thanks, Will! I like these plots 😊

Hello Strangers,

As promised I will send you my cuts/event selection for the plots I have been showing:

Data: Skim14 (Electron in FD, k+ anywhere)

Event selection:
1 e^- in FD
1 pi^- anywhere
1 k+ anywhere
1 proton anywhere

Cuts:
k+ momentum < 2.0 GeV
Missing Mass^2 off of reconstructed particles (4 tracks) < 0.05 GeV^2
New** = Missing Momentum < 0.1 GeV

Assumption: e^- beam energy set to 10.614 for MM calculations (I should look into this…).

Sorry Eugene, you’ll have to wait for the suggested plots until after I finish writing this midterm!

-Will
