Aspects of the unitarized soft multipomeron approach in DIS and diffraction
We study in detail the main features of the unitarized Regge model (CFKS), recently proposed to describe the small-\(Q^2\) domain. It takes into account a two-component description with two types of unitarized contributions: one is the multiple pomeron exchange contribution, interacting with the lar...

| description | We study in detail the main features of the unitarized Regge model (CFKS), recently proposed to describe the small-\(Q^2\) domain. It takes into account a two-component description with two types of unitarized contributions: one is the multiple pomeron exchange contribution, interacting with the large dipole size configurations, and the other one consists of a unitarized dipole cross section, describing the interaction with the small size dipoles. We analyze the ratio between soft and hard pieces as a function of the virtuality, and also compare the resulting dipole cross section to that from the saturation model. Diffraction dissociation is also considered, showing the scaling violations in diffractive DIS and estimating the corresponding logarithmic slope. |
