This is a short desciption of several pion events that were run
through GEANT. Twelve Pion Laser events were generated by Ron
Longacre and labeled laser_XXX_auau.txt, where XXX are 150, 151,
152, 250, 251, 252, 350, 351, 352, 500, 501, 502, referring
to the momentum of the laser. These events were run through the
full STAR GEANT and the hits on the Trigger detectors were stored
in the files laser_XXX_auau.fzd. The eta-phi distributions of
hits on the CTB are shown in figures 1,
2 and 3.
From these figures, it is apparent that when the momentum of the
laser is below 200 MeV/c, the phi vs. eta correlation is gone.
