Abstract

In this paper, we present the experimental analysis of the parameter T (temperature) as a function of the cumulative number n_c of π^– - mesons, K₀ - mesons and protons produced in π^– C interactions at 40 GeV/c. On the basis of this analysis, we determined a dependence between the half mass of the particle (m_i/2) and the target mass value (m_c = m_pn_c), which is required from the target for the production of the particle. We suggest that the dependence between the two masses mentioned above may be related to the beginning of the mixed phase with constant temperature.
