  • Using quantum pathintegral formulae,we examined the twokaon and twopion HanburyBrownTwiss (HBT) interferometry for the particleemitting source with high baryon density. The evolution of the source is described by relativistic hydrodynamics. We use an equation of state of firstorder transition from QGP to hadronic phase and consider a volume correction for the hadronic gas. The twopion HBT results with effects of excitedparticle decay and multiple scattering were investigated and compared with those for conventional thermal freezeout (TFO) model. We found that the twokaon HBT radius was smaller than those of the twopion interferometry. The particle decay increases the HBT radius and lifetime, while the effect of multiple scattering on HBT results can be neglected.
