The hadron production in π−-C interaction at 40 GeV/c and QCD phase transition

In this paper, we proposed to study the phase transition process to use the new pair of variables, the temperature T and the cumulative number n c (T, n c ). We considered the transverse energy spectra of protons and π − -mesons produced in π − -C interactions at 40 GeV/c as a function of cumulative number n c (or four-dimensional momentum transfer t) and the baryonic chemical potential μ b (√ t ). Obtained results indicate the possible appearance of QCD phase transition of nuclear matter.
