Abstract

We demonstrate the occurrence of canonical suppression associated with the conservation of a U(1) charge in current transport models. For this study a pion gas is simulated within two different transport approaches by incorporating inelastic and volume-limited collisions \ensuremathπ\ensuremathπ\ensuremath↔KK for the production of kaon pairs. Both descriptions can dynamically account for the suppression in the yields of rare strange particles in a limited box, being in full accordance with a canonical statistical description.
