DESCRIPTION:The asymmetries in ep-scattering allow one to access the imagi
 nary part of the doubly virtual Compton scattering amplitude. At high ener
 gy and momentum\, the latter can be described in terms of the Generalized 
 Parton Distributions.I present a handbag calculation for the beam normal s
 pin asymmetry B_n\, discuss the validity of the equivalent photon approxim
 ation for this observable and show that this asymmetry gives a unique poss
 ibility to access the helicity-flip gluon GPDs.\n\nhttps://indico.ific.uv.
