Re: Another update of the PID talk



Hall D PID Mail List:


I changed the document 1011 again.
I fixed a wrong notation on page 19. In the table there
there are values for rate suppression, labled as BG suppression,
which is not the same for small BG.
In the new version I replaced them with the "real" BG suppression factors,
which are much larger for the PID (the total PID factor is about 80).

Also, I added a line on an 1C fit result.
For the same MC events I removed the proton and tried to make the 1C
fit assuming the proton mass. I obtained signal/BG of about 1:5,
instead of 10:1 for the overdefined kinematics. The PID suppression
factor was about 10.
