| Research Abstract |
Boltzmann-Vlasov equation in the SU(2) gauge theory in which elastic scattering between plasma particles are incorporated has been performed. We showed that numerical results is independent of lattice size in our particle-cell simulation. Therefore we can extract transport coefficients consistently. We also compute gluon distributions in the initial stages of nuclear collision in which fluctuations from both gluon production itself and the position of nucleons in nucleus are included. It is found that the effects of these fluctuations have very important contributions to the higher order flow coefficients in the initial spacial distribution
