Large Rapidity GaP Events and Reggeon in DIS

  • The experimental results on maximum pseudo-rapidity ηmax distribution in the charge exchange process e+p→e+n+X is discussed in thes paper. The contributions of reggeon from regge phenomenology and π+ -exchange from pion cloud medel is calculated. The results show that neither the Rρ-exchange nor the pion cloud model alone can explain the experimental data well, but after considering both these two processes together, by using Month Carlo simulahon, a good agreement betWeen theoretical results and experimental data is found.

Abstract: The experimental results on maximum pseudo-rapidity ηmax distribution in the charge exchange process e+p→e+n+X is discussed in thes paper. The contributions of reggeon from regge phenomenology and π+ -exchange from pion cloud medel is calculated. The results show that neither the Rρ-exchange nor the pion cloud model alone can explain the experimental data well, but after considering both these two processes together, by using Month Carlo simulahon, a good agreement betWeen theoretical results and experimental data is found.
