[Clas12_dileptons] HTCC and track sector studies

[Rafayel Paremuzyan]

Hello Stapan,

thank you for slides.

To me pid cuts are pretty reasonable.
I assume exclusivity cuts are |MM2| < 0.1 GeV^2  AND Q2 < 0.1 GeV^2

when Richard will post his slides, we can have a look into his cut values.

However one thing that I think is different is that you require
sector of the track to be the same as the sector of HTCC,
while for trigger studies we required sector of HTCC to be the same as the sector of PCal and EC_in (nothing
required on track sector).
I am not sure how much difference this will make (if any), but if it is not too much of work, could
you require PCal and HTCC sectors to be the same, instead of track and HTCC sectors.

p.s. also could you make the comparison plot in a linear scale.

Hello all,

Attached are a few slides I put together to study the HTCC-track sector mismatch. Yes, there are positrons with odd sector combinations, especially for p<4.8 GeV. But in the end, it makes no difference for my invariant mass distribution.
