摘要：We discuss HERA data on the high energy behavior of the total p cross
section and on di
raction in DIS. A natural link between inclusive and di
ractive p
processes is provided by the dipole description of DIS. In the dipole picture the hard and
soft interaction regions can be connected by the saturation hypothesis which leads to a
good description of HERA measurements. An extension of the saturation ansatz by the
evolution e
ects improves sizably the agreement with data.
