Inclusive characteristics of π--mesons produced in pC and pTa interactions at 10 GeV/c proton momentum

New data on inelastic pC and pTa interactions at an incident proton momentum of 10 GeV/c have been obtained in the inclusive approach for 4π geometry. The distributions of secondary π- mesons over different kinematic variables have been studied. These distributions are compared with analogous ones for an incident proton momentum of 4.2 GeV/c well as with predictions of a Dubna version of the cascade-evaporation model. The model is shown to describe well the π--meson experimental distributions over momentum up to ∼ 6 GeV/c, over transverse momentum squared up to ∼ 1 (GeV/c)2, as well as over rapidity in the central region. At the same time, the model differs substantially from the experiment in the region of projectile and target fragmentation and also in the multiplicity distribution of π- mesons
