Effect of relaxation time on the squeezed correlations of bosons for evolving sources in relativistic heavy-ion collisions
文献摘要：
The squeezed back-to-back correlation(SBBC)of a boson-antiboson pair is sensitive to the time distri-bution of the particle-emitting source,and the SBBC function for an evolving source is expected to be affected by the relaxation time of the system.In this study,we investigated the effect of relaxation time on the SBBC function.We propose a method for calculating the SBBC function with relaxation-time approximation for evolving sources.SBBC functions of D0(D-)0 in relativistic heavy-ion collisions were investigated using a hydrodynamic model.We found that the relaxation time reduces the amplitudes of the SBBC functions.This becomes apparent for long relaxation times and large initial relative deviations of the chaotic and squeezed amplitudes from their equilibrium values in the temporal steps.
