On the $m_{\perp }$-dependence of Bose-Einstein correlation radii

Abstract

Within a theoretical study using both HYLANDER and RQMD, we revisit Bose-Einstein correlation measurements of 200AGeV S+S and 160AGeV Pb+Pb. Transverse flow does not show up in the Bose-Einstein measurements. The decrease of the effective transverse radius parameters with increasing transverse average momentum of the particle pair is largely due to the effect of resonance decays.
