| contents | The possibi;lity of a probabilistic interpretation is studied for the Regge-Gribov model in zero dimensional transverse world ("Toy") with interacting pomerons and odderons. It is found that the previously proposed recipe to introduce such interpretation in the model without odderons, does not work once odderons are included. Starting from the physically reasonable probabilites it leads to a pathological field theory violating $C$-parity invariance. Inversely, starting from an admissible field theory one comes to pathological probabilities, which not only violate $C$-nvariance but also allow particles to be created from or annihilated into the vacuum. A method is proposed to introduce reasonable probabilities besed directly on the Fock components of the wave function. Such probabilities manifest themselves in the multiplicity distributions of hadrons produced in high-energy collisions. The corresponding entropy grows with rapidity but saturates in the limit. It is found to be similar for processes of both parity exchanges. |
