Abstract

We apply the generalized Veneziano model (B5B_5 model) in the double-Regge exchange limit to the γpK+Kp\gamma p \to K^+ K^- p reaction. Four different cases defined by the possible combinations of the signature factors of leading Regge exchanges ((K,a2/f2K^*,a_2/f_2), (K,ρ/ωK^*,\rho/\omega), (K2,a2/f2K_2^*,a_2/f_2), and (K2,ρ/ωK_2^*,\rho/\omega)) have been simulated through the Monte Carlo method. Suitable event candidates for the double-Regge exchange high-energy limit were selected employing \textit{Van Hove} plots as a better alternative to kinematical cuts in the K+KpK^+ K^- p Dalitz plot. In this way we predict and analyze the double-Regge contribution to the K+KpK^+ K^- p Dalitz plot, which constitutes one of the major backgrounds in the search for strangeonia, hybrids and exotics using γpK+Kp\gamma p\rightarrow K^+K^-p reaction. We expect that data currently under analysis, and that to come in the future, will allow verification of the double-Regge behavior and a better assessment of this component of the amplitude.
