摘要：We calculated the rate of exclusive multihadronic channels in the statistical hadronization model within a fullmicrocanonical framework by enforcing themaximal set of conservation laws including energy-momentum, angular momentum, parity, as well as isospin, C-parity and charges. A preliminary test has been performed by comparing model predictions against a set of two-mesons channel rates measured in pp annihilation at rest. The same comparison has been made for the phase space dominance model. The analysis suffers from the complication of the annihilation process which proceeds from many initial pp atomic bound states, thus requiring the introduction of several free parameters. Both models prove to reproduce the general trend of the experimental data although the agreement with the specific values is not satisfactory.
