Hello,
I see, sometimes many, negative particles with ect/p = ecin/p ..
Are these particles most probably pions or electrons? I put four
pictures to the secure site that shows these particles in ecinp vs ectp
distributions. Please visit the link:
http://www.jlab.org/Hall-B/secure/eg1/EG2000/nevzat/EC_Dist/
And a second less important question: I see many particles with ecin/p =
0 or ect/p = 0.. I see a huge peak at zero in my pion (both pi+ and pi-) selections.
ect/p distribution or ecin/p distribution for pions goes to zero smoothly but a
huge peak appears at zero, which supresses the distribution to make it almost
invisible. I put ecinp_pim.gif and ect_pim.gif in the same EC_Dist directory
(the above link). In those pictures I cut out the the peak at zero to make the
rest of the pions visible to show how it goes to zero..
The question is that are these particles that appear at zero really pions?
Thanks for your inputs..
Nevzat.
