Also, I forgot that we made sure the kaon was reconstructed in the FD in order to attempt to cleanup the missing mass plot. Hope this helps anyone trying to reproduce this. And for anyone trying to reproduce this we should check out Dan Carman’s work.

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
