Abstract Using the relativistic quantum molecular dynamics approach,
with a correlation after-burner, the physics of transverse momentum dependence of the Hanbury-Brown and Twiss parameters is studied for Au + Au, Si + Si and p + p collisions at the center-of-mass energy √s = 200AGeV. The results indicate that the space-momentum correlations would affect such dependence in both heavy-ion and elementary collisions. The size parameters as a function of the transverse mass mt are sensitive to the degree of space-momentum correlations.
