    "abstract": "The thermodynamic potential of a system of pions and nucleons is computed\nincluding the piN interactions in the P33 channel. A consistent treatment of\nthe width of the resonance in this channel, the Delta(1232) resonance, is\nexplored in detail. In the low-density limit we recover the leading term of the\nvirial expansion for the thermodynamic potential. An instructive diagrammatic\ninterpretation of the contributions to the total baryon number is presented.\nFurthermore, we examine within a fireball model the consequences for the pion\nspectra in heavy-ion collisions at intermediate energies, including the effect\nof collective flow. A consistent treatment of the Delta width leads to a\nsubstantial enhancement of the pion yield at low momenta.",
