Inclusive cross sections of cumulative π--meson production in π-C interactions at 40 GeV/c as functions of kinetic and transverse enegy

Invariant distributions of the kinetic and transverse (Et =√ pt2+m2 energies on cumulative π--mesons produced in π-C interactions at 40 GeV/c are investigated. The experimental spectra slopes correspond to the temperature of cumulative π--meson production T0≅300 MeV. This value is higher than the theoretical estimations for the critical temperature of a phase transition from the hadron matter to the quark-gluon plasma Tc≅200 MeV. May be it indicates to the fact that the quark-gluon plasma is produced in the local region of cumulative π--meson production. 27 refs.; 5 figs.; 2 tabs
