Peripheral processes 2→3 and 2 → 4 in QED and QCD in p(p?)p high-energy collisions

摘要

Differential cross sections of processes with high-energy p(p?)p collisions-creation of a scalar, a pseudoscalar and a lepton pair-are considered in the Weizsacker-Williams approximation in QED in the QCD framework, processes with conversion of the initial proton (antiproton) to fermionic jets accompanied with one gluon jet and the state of two gluons and a quark-antiquark pair (without a rapidity gap) are considered in the framework of the effective Regge action of Lipatov's theory. The process of creation of a Higgs boson accompanied with two fermionic jets is considered. The azimuthal correlation in the process of two gluon jets separated by a rapidity gap is investigated. The gluon Reggeization effects are taken into account. Some distributions are illustrated by numerical calculations.
