%0 Journal Article %T Entropy production by resonance decays %A Stefan Ochs %A Ulrich Heinz %J Physics %D 1996 %I arXiv %R 10.1103/PhysRevC.54.3199 %X We investigate entropy production for an expanding system of particles and resonances with isospin symmetry -- in our case pions and $\rho$ mesons -- within the framework of relativistic kinetic theory. A cascade code to simulate the kinetic equations is developed and results for entropy production and particle spectra are presented. %U http://arxiv.org/abs/hep-ph/9606458v2
