### Abstract

We study to what extent a measurement of the m_{⊥} spectra for hadrons and their resonances can resolve ambiguities in the statistical model description of particle production. We describe in a quantitative analysis how physical assumptions about the freeze-out geometry and dynamics influence the particle spectra. Considering ratios of m_{⊥} distribution of resonance-particle ratios (such as K*/K, Σ*/λ, η′/η) we observe significant sensitivity to fireball freeze-out geometry and flow dynamics.
