Abstract:
We calculate the net baryon rapidity
distribution in Au+Au
collisions at the Relativistic Heavy Ion
Collider (RHIC) in
the framework of the Parton Cascade Model
(PCM). Parton
rescattering and fragmentation leads to a
substantial
increase in the net baryon density at
mid-rapidity over the
density produced by initial primary parton-parton
scatterings. The PCM is able to describe the
measured net
baryon density at RHIC.
