摘要: We have studied the evolution and dilepton production of a chemically equilibrating quark-gluon plasma considering finite baryon density based on Juttner distribution partons, found that due to increasing quark phase life-time with initial chemical potential, high temperature, large gluon system as well fusion gg --> c (c) over bar cross section in intermediate mass region, quark-antiquark annihilation q (q) l (l) bar, especially, thermal charmed quarks from provide dominant contribution dileptons, resulting significant enhancement dileptons.
