Abstract: (Elsevier)
Single-particle inclusive data from p p annihilation experiments at 4.6 and 9.2 GeV/ c are displayed, and compared with other data from N N and e + e − annihilation reactions. The single-particle distributions are found to be exponentially peaked and almost isotropic at small momenta in the centre of mass. The temperature, or exponential slope of this distribution, is well fitted by a linear form in s −1 2 , extrapolating to an “ultimate temperature” of 164 ± 5 MeV. These results are in accordance with the hypothesis that the annihilations very often give rise to the formation of single clusters, whose decay can be described by the statistical bootstrapmodel. Attempts to isolate a class of events corresponding to single cluster formation are discussed.
