Minimized economical interactions

The idea of economical interaction is suggested according to which inclusive particle production in extremal situations is determined by minimum possible total energy of colliding constituents. Experimental data on cumulative production cross sections of pions and kaons depending on minimum possible interacting constituents energy are given. It is shown that inclusive reactions of various types, cumulative processes at large orders of cumulativity and processes with large transverse momenta are described by an unit universal function of minimum possible total energy of colliding constituents, minimized masses of which are determined by kinematics of inclusive particle production
