Impact parameter dependent distributions in exclusive processes
Within hard scattering approaches, high energy exclusive reactions
are expected to be dominated by
small hadronic transverse size configurations.
A possible experimental validation of this picture
can be obtained by studying the phenomenon of color transparency, that is
by monitoring the passage through the nuclear medium of such small
separation components. However, current interpretations of the onset of
color transparency are still ambiguous.
We discuss a new tool given
by generalized parton distributions in the impact parameter representation,
to better constrain the size and role of small transverse separations
components in hadronic structure.
We also analyze the relation between transverse momentum
components and transverse separations.
