A theory is proposed for the phenomena related to the masses M and transverse momenta p/sub perpendicular/ for 1 GeV< or approx. =M and pperpendicularvery-much-less-than..sqrt..s. The model of a quark-gluon plasma in local equilibrium expanding according to a certain law is used. The use of quantum chromodynamics to calculate reaction rates in this plasma permits us to obtain the dilepton mass spectra, the perpendicular distributions of leptons, photons, pions, and hadronic jets, and the cross sections for producing charmed quark pairs and various charmonium states (psions): J/psi, chi, and chi' mesons. The results are compared with the experimental data.
