Reading the 999 paper and your presentations I realized
that the difference is significant and starts, perhaps, at the initial
resolutions. However, the track resolutions I use (taken from David) are
similar or only slightly worse than those you show on page 5 of your
presentation.
Let us consider the reactions you used:
1) gp->pK+pi+K-pi-
2) gp->ppi+pi+pi-pi-
These reactions are identical in the 3-momentum space. The only
difference is the energy. It is a 1-dim. separation.
I obtained the E_final-E_initial resolution of sigma=150 MeV
(180 MeV for some PYTHIA events, perhaps because of a different energy
distribution). The reaction 2), treated as 1) gives an average energy shift
of 120MeV, which is 0.8 sigma of one peak. So, I get a rather small separation...
What are your values for these resolutions/separations?
Thanks,
Eugene
