Single spin asymmetries in elastic ep-scattering with transverse spin
Mikhail Gorshteyn (Universitá di Genova)
Aula de Seminaris de Física Teòrica

Resum
The asymmetries in ep-scattering allow one to access the imaginary
part of
the doubly virtual Compton scattering amplitude. At high energy and
momentum, the latter can be described in terms of the Generalized Parton
Distributions.I present a handbag calculation for the beam normal spin
asymmetry B_n, discuss the validity of the equivalent photon
approximation
for this observable and show that this asymmetry gives a unique
possibility to access the helicity-flip gluon GPDs.
