Abstract
The rapidity distributions of inclusive π+ p → π−,K 0, Λ0 andK * (892) atP 1ab=16 GeV/c of CERN experiments, are analyzed using the covariant partition temperatureT p model. In the fireball system, apart fromK * (892),T *p <m, no indication of thermal equilibrium, the average momentum\(\sqrt {3mT_p^* }\) ofK 0 andΛ 0 being approximately equal and in the opposite direction, the entropy density is practically the same forK 0 andΛ 0 but less than that of π−. It is found that the principle of equipartition holds rather for the momenta of π,K, and Λ in the fireball system.
