Hi Harut,

Thanks for adding the slides. Did we ever validated the ratio for CLAS12 on slide 19. I believe we have data with type of triggers (presecaled) that will allow to validate that MC ratio.

Regards, Stepan

Dear All,

Sorry the original version went to wrong list.

I updated slides in https://userweb.jlab.org/~avakian/tmp/2022-Hall-B-Wednesday.march23.pdf
2 additional slides 19 and 20 now show the relative rates of pi-/e- and Kaon/pion ratios, as requested by Stepan.
The ratios were produced using the Weiser fits from Peter Bosted. The ratios increase 30-50% from CLAS12 to CLAS22.
We will check them with PYTHIA. While the pi-/e- ratios come reasonable, we know that the ratio of kaons to pions is x2-3 to high in Weiser fit compared to our data and MC.
Best regards,

P.s. The late start is due to a conflict with a mandatory meeting that some of us have to attend. Sorry for inconvenience.
