Abstract

We investigate deuteron two-body photodisintegration within the framework of the Quark-Gluon Strings Model with nonlinear baryon Regge trajectories. Special attention is paid to the use of QCD motivated Regge trajectories of the logarithmic and square-root form which have been suggested recently by Brisudov\'{a}, Burakovsky and Goldman. We find that the recent experimental data from TJNAF in the few GeV region can reasonably be described by the model. Angular distributions at different γ\gamma-energies are presented and the effect of a forward-backward asymmetry is discussed. Predictions for the energy dependence of dσ/dtd\sigma/dt at higher energies and different Θcm\Theta_{cm} are presented, too.
