The effect of single-particle space-momentum angle distribution on two-pion HBT correlation in relativistic heavy-ion collisions using a multiphase transport model

【摘要】 Using the string melting version of a multiphase transport(AMPT) model, we analyze the transverse momentum dependence of the HBT radius R_s and the single-pion angle distribution on the transverse plane in central Au+Au collisions at ■, and 200 GeV. Additionally, a numerical connection between these two phenomena is established with a series of functions. We can estimate the single-pion angle distribution on the transverse plane from HBT analysis.更多还原
