Relationship between particle freeze-out distributions and Hanbury Brown–Twiss radius parameters

The relationship between pion and kaon space-time freeze-out distributions and the Hanbury Brown--Twiss (HBT) radius parameters in high-energy nucleus-nucleus collisions is investigated. We show that the HBT radius parameters in general do not reflect the rms deviations of the single particle production points. Instead, the HBT radius parameters are most closely related to the curvature of the two-particle space-time relative position distribution at the origin. We support our arguments by studies with a dynamical model (RQMD 2.4).
