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

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.
