QCD dipole prediction for DIS and diffractive structure functions

Abstract

The $F_2$, $F_G$, $R=F_L/F_T$ proton structure functions are derived in the QCD dipole picture of BFKL dynamics. We get a three parameter fit describing the 1994 H1 proton structure function $F_2$ data in the low $x$, moderate $Q^2$ range. Without any additional parameter, the gluon density and the longitudinal structure functions are predicted.The diffractive dissociation processes are also discussed, and a new prediction for the proton diffractive structure function is obtained.
