GCP Code Applied in J/ψ Production and Absorption
Xiao-Xia Yao, Wei-Qin Chao, Yang Pang
Abstract
Using the General Cascade Program(GCP), the production and absorption of J/ψ in p-A and A-A collisions have been studied. Nucleon absorption mechanism and comover absorption mechanism are considered to investigate the J/ψ suppression. The results agree well with experimental data of J/ψ production, except for the data in Pb-Pb collision.
