Dear Yoshitaka and WG5 conveners,
Samuel Wallon emailed me about his postdoc, Saad Nabeebaccus, who didn't
put in an abstract in time. He said that he first contacted you as it would
be a better fit in your working group, but that was before the additional
slots became available. Were you planning to accept their talk now? If not,
then we would like to give them one of the extra talk slots in our WG, but
I wanted to check with you first as I also think it's a better fit in the
Imaging / Spin session.
Saad sent me his abstract by email:
Title: "Accessing GPDs through the exclusive photoproduction of a
gamma-meson pair".
Abstract:"We consider the exclusive photo-production of a gamma-meson pair,
working in the QCD factorisation framework. Explicitly, we consider a rho
meson and a charged pion in the final state. This process has a significant
advantage over meson production, since it allows us to probe chiral-odd
GPDs, which are not well-known experimentally. The computation is performed
at leading order and leading twist, and we intend to extend this to ${\cal
O}(\alpha_s)$ soon. We discuss the prospects of measuring them in
experiments, and in particular focus JLab and LHC (in UPC) kinematics."
Thanks,
Daria
