Hard non-vacuum reggeon in the CKMT model
V. A. Abramovsky, A. V. Dmitriev
Abstract
The CKMT model describing the nucleon structure function F2(x,Q2) in the framework of conventional Regge theory with smooth soft-hard pomeron is modified. Smooth soft-hard non-vacuum reggeon dependence on incoming photon virtuality Q2 is introduced. This dependence has the same functional form as the smooth soft-hard functional Q2 dependence for pomeron in original CKMT model. In regeon of low W2 better agreement with experimental data is observed.
