[Clas12_first_exp] [EXTERNAL] Re: Joint RGA/RGB meeting 11/16/22 @ 8:00 AM - Note time Change 8:00 AM

[harut avagyan]

Dear All,
I updated the slides on Lambda analysis. The proton distributions are
added, and an additional cut on the vertex introduced to eliminate the
Lambda decays beyond the target limits.
https://userweb.jlab.org/~avakian/tmp/2022-Nov-15-Lambda.pdf
The difference in momenta for pions ~ 0.4-0.6 GeV stays there. There is no
difference (shoulder) for protons (selide 13). It appears that in our
generated Lambda sample, there are very few protons< 500MeV, so we will
need some other process (DVCS) to check the impact on proton momentum below
600MeV.
Otherwise the momentum difference is similar to pions. The energy loss
correction below 0.6 GeV may require additional checks.
Best regards,
Harut
