The single-particle space-momentum angle distribution effect on two-pion HBT correlation with the Coulomb interaction
arXiv:2201.00998 · doi:10.1088/1674-1137/ac8c23
Abstract
We calculate the HBT radius Rs for π+ particles with the Coulomb interaction by using the string melting version of a multiphase transport(AMPT) model. We study the relationship between the single-particle space-momentum angle and the particle sources and discuss HBT radii without single-particle space-momentum correlation. Additionally, we study the Coulomb interaction effect on the numerical connection between the single-particle space-momentum angle distribution and the transverse momentum dependence of Rs.
