Abstract

In this talk, we present a global analysis of available small -x data on inclusive DIS and exclusive diffractive processes, including the latest data from the c ombined HERA analysis on reduced cross sections within the Impact-Parameter dependent Saturation (IP-Sat) Model. The impactparameter dependence of dipole amplitude is crucial in order to have a unified description of both inclusive and exclusive diffractive processes. With t he parameters of model fixed via a fit to the high-precision reduced cross-section, we compare model predictions to data for the structure functions, the longitudinal structure function , the charm structure function, exclusive vector mesons production and Deeply Virtual Compton Scattering (DVCS). Excellent agreement is obtained for the processes considered at small x in a wide range of Q 2 .
