Double-Regge exchange limit for the γp →kp reaction

We apply the generalized Veneziano model (B5 model) in the double-Regge exchange limit to the γp→Kp reaction. Four different cases defined by the possible combinations of the signature factors of leading Regge exchanges +AFs-(K∗,a2/f2), (K∗,ρ/ω), (K2∗,a2/f2), and (K2∗,ρ/ω)+AF0- have been simulated through the Monte Carlo method. Suitable event candidates for the double-Regge exchange high-energy limit were selected employing Van Hove plots as a better alternative to kinematical cuts in the Kp Dalitz plot. In this way we predict and analyze the double-Regge contribution to the Kp Dalitz plot, which constitutes one of the major backgrounds in the search for strangeonia, hybrids and exotics using γp→Kp reaction. We expect that data currently under analysis, and those to come in the future, will allow verification of the double-Regge behavior and a better assessment of this component of the amplitude.
