Resonance production in the hydrodynamical model

Presented is a modified hydrodynamic model for the cross section set description of PI-, rho0, ω, f, eta particle direct production, secondary particle composition and their distributions on the square of transverse momentum. The suggested model presupposes, that production of every particle type takes place at the temperature T approximately M, but the produced particles continue to cool down, participatin.o in adiabatic expansion of the hydrodynamic model. This approach permits to take account of resonance production within the frames of the hydrodynamic theory; it does not contradict experimental data and it approximately describes their set
