采用结合不确定性原理的彩色玻璃凝聚（CGC）破碎法，得到了相对论重离子碰撞后的初始相空间分布，并求解了包含胶子辐射过程的半经典玻尔兹曼方程。我们给出了在相对论性重离子碰撞后形成的介质中，横向动量大于6 GeV/c的高p(T)部分的衰减率作为时间的函数。我们计算了椭圆流作为冲击参数、时间和横向动量的函数，并给出了极性各向异性，这为彩色细丝的形成提供了初始条件。
We obtain the initial phase space distribution just after relativistic heavy ion collision by using the Color Glass Condensate (CGC) shattering method incorporating the uncertainty principle and solve the semi-classical Boltzmann equation that includes the gluon radiation processes. We present, as a function of time, the attenuation rate of high p(T) partons, which have transverse momenta over 6 GeV/c, in the medium that is formed after relativistic heavy ion collision. We calculate the elliptic flow as a function of an impact parameter, the time, and the transverse momentum and present the polar anisotropy, which gives the initial condition for color filamentation.
