What about the contribution from reggeons in hard process of strong interactions?
Abstract
We discuss in this paper the possible contributions from R_\rho(\rho-reggeon associated with \rho meson) in DIS process on protons. Using results from phenomenological analysis of high energy \pi-N charge-exchanged scattering process, we get the expression of effective propagator of R_\rho and the coupling constant \beta_\rho between R_\rho and light quarks. As a simple and concrete example, we use them to evaluate the contributions of R_\rho to F_2(x,Q^2) from charge-exchanged photoproduction quark-pair process,\gamma^* + p-->n + q_u + \bar{q}_d (--> n + X), in HERA kinematical regions. For a comparison, we also evaluate contributions both from pomeron and partons in the same process. The ratio of contributions in F_2(x,Q^2) from R_\rho versus IP is larger than 1%, therefore, the former may be tested experimentaly.
