[Bonuslist] [EXTERNAL] Re: Next BONuS Meeting tomorrow

[mhattawy@odu.edu]

Dear all,
   Following our meeting yesterday regarding having two dips in vz around
zero after the dEdx cut, I have generated a few millions of protons flat in
the detection phase-space of the RTPC. The results can be found here
https://userweb.jlab.org/~hattawy/bonus_analysis/rgf_simulation_analysis/rgf_flat_protons.pdf
Given that the two dips have only being seen in the radiative elastic data
(Figs 7 and 8 in
https://userweb.jlab.org/~hattawy/bonus_analysis/rgf_simulation_analysis/rgf_2.1elastic_nov182021.pdf)
and not in the inelastic 2.1GeV data (
https://userweb.jlab.org/~hattawy/bonus_analysis/rgf_simulation_analysis/rgf_2.1inelastic.pdf)
neither in the ep (+20 accidental protons /event) in
https://userweb.jlab.org/~hattawy/bonus_analysis/rgf_simulation_analysis/rgf_ep_20protons.pdf
NOR in the recent flat generated protons as above, THEN I would conclude
that this is mostly an issue with the generated elastic data.

Best regards,
Mohammad
