Study on the pp → ppπ+π- reaction in the framework of one pion exchange Regge model

In the reggesized one- pion exchange model (OPER) with parameters fixed previously when describing general characteristics of the pp → ppπ+π- reaction the author investigates the angular distributions in the centre-of-inertia systems of the pπ+ and pπ- pairs in the reaction. The quasithreeparticle reaction pp → pπ-Δ++(1236) is described in detail. The effect of cone 'broadening' on the production of the pπ+π- system with the growth in the mass of the system is calculated. The two-reggeon area of the pp → pπ-Δ++ - reaction is described. When describing all characteristics it has been found that the theory agreed well with experimental data
