Hard non-vacuum reggeon in the CKMT model
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.
