    • Abstract

       

      A model for high energy proton-proton system is developed which obeys several asymptotic bounds including Froissart bound. The amplitude taken has two parts, a Regge part and a pomeron part. The Regge part is described by the exchange degenerate pairw andP′. To calculate the pomeron part the Freund-Harari duality is invoked which states that the pomeron is dual to thes-channel background. Thes-channel background is estimated by parametrising the branch cuts inS through a conformal mapping method. Expressions for total cross-section, ratio of real-to-imaginary parts of forward amplitude and the slope parameter are presented. The corresponding quantities for$$p\tilde p$$ are also evaluated. Our analysis favours strong exchange degeneracy.
