摘要: Abstract Based on the microscopic transport model UrQMD in which hadronic and string degrees of freedom are employed, HBT parameters longitudinal co-moving system investigated for charged pion kaon, Λ sources heavy ion collisions (HICs) at SPS RHIC energies. In Cascade mode, R O L high energies do not follow m T -scaling, however, after considering a soft equation state with momentum dependence (SM-EoS) formed baryons density-dependent Skyrme-like potential “pre-formed” particles, radii pions kaons even those Λs large transverse momenta -scaling function = 3 / fairly well.
