Kaon Interferometry at RHIC from AMPT Model

Abstract

The two-kaon interferometry at RHIC is studied in a multi-phase transport model. Similar to the pion case, we find strong space-time correlation at freeze-out for the kaon emission source, which results in a large positive $R_{\mathrm{out}}-t$ term and tends to reduce the $R_{\mathrm{out}}/R_{\mathrm{side}}$ ratio. Unlike the pion case, the source radii for kaons determined from the emission function are close to the radius parameters extracted from a Gaussian fit to the correlation function.
