Summary of this research (10-100 lines)
This is a simulation project of RHIC-PHENIX experiment.
We will generate about 2e9 pi0, according to the production cross
section in sqrt(s_{NN})= 200 GeV d-Au collisions, and evaluate
the spectrum of single electrons coming from pi0 Dalitz decays and
gamma conversions.  We also evaluate the effect of the photon converter,
which was a blass cylinder of thickness of 0.01 inches and was installed
to evaluate the spectrum shape of conversion electrons..
The kinematic region of pi0 is -0.5--0.5 in
rapidity, 0.5--10 in transverse momentum, 2 pi-- in phi and
-30 -- 30 in vertex-z.  The acceptance of the simulation is the
central arms of RHIC-PHENIX experiment.  We use PISA2000 and a
reconstruction cord of PHENIX official, whose versions are pro.54.
Anyway, this need huge computing power.
Thus, we will make a proposal to RCCS as soon as possible.
