摘要
A model for total cross sections with virtual photons is presented, in particular gamma-p and gamma-gamma cross sections are considered. Our approach is based on an existing model for photoproduction, which subdivides the total cross section into three distinct event classes: direct, VMD and anomalous. In the region of large photon virtualities, the Deep Inelastic Scattering processes (up to O(alpha_s) corrections) are obtained. Hence, the model provides a smooth transition between the two regions. By the breakdown into different event classes, a complete picture of all event properties is the ultimate goal.
