On production of large diffraction masses in high-energy nucleon collisions

Production of large diffraction masses in collisions of gluon clusters of nucleons are investigated. Exclusive quark distributions are obtained from solution of nonlinear integral equations. Solutions for uu and ud diquarks have been found. From comparison of the solutions obtained and experiment behaviour of structure functions of valent quarks u(x) and d(x) at x→1 in the processes with small transferred momenta has been found. Dependence of exclusive distributions and spectra of leading protons on transverse momenta is investigated. Collisions of gluon clusters is described by hydrodynamical picture. Rapidity distributions and multiplicity of secondary particles in the diffraction region have been calculated. A quantitative agreement with experimental data obtained at the collider has been found. 24 refs.; 9 figs
