Statistical Hadronization probed by resonances

Abstract

We study to what extent a measurement of the $m_{\perp }$ spectra for hadrons and their resonances can resolve ambiguities in statistical model description of particle production. We describe in quantitative analysis how physical assumptions about the freeze-out geometry and dynamics influence the particle spectra. Considering ratios of $m_{\perp }$ distribution of resonance-particle ratios (such as $K^{\ast }/K$, ${\Sigma }^{\ast }/\Lambda ,{\eta }^{\prime }/\eta$) we observe significant sensitivity to fireball freeze-out geometry and flow dynamics.
