Production of high energy cumulative hadrons in proton-nucleus interactions

New results of measuring invariant cross sections of pA → pX reaction for 0.6-1.83 GeV/c secondary proton momenta are presented. Experiment was conducted in internal beam of ITEP synchrotron at 5 and 10 GeV proton energies. Dependencies of invariant cross section on proton kinetic energy, on X cumulative number were obtained. The dependence of the ratio of invariant cross sections on different nuclei on X, the dependence of universal f0 function on X cumulative member are presented. It was concluded, that cumulative processes were described by the universal f0 function, independent of mass number of A nucleus and on Eo initial energy at Eo >or approx. 10 GeV, parameter of F0 function slope doesn't depend on the angle of proton escape for x > 1.8. The observed change of f dependence on Pt and intensive K+-meson production can testify to formation of a new state of nuclear at achieved energies matter
