Title Title Parton Distributions in Impact Parameter Space
Topic Oral
Abstract of 200 words or less
Parton distributions in impact parameter space, which
are obtained by Fourier transforming GPDs, are exhibit
a significant deveiation from axial symmetry when the
target and/or quark is transversely polarized. In
combination with the final state interactions, this
transverse deformation provides a natural mechanism for
naive-T odd transverse single-spin asymmetries in
semi-inclusive DIS. The deformation can also be related
to the transverse force acting on the active quark
in polarized DIS at higher twist.
