Proton mass effects in wide-angle Compton scattering
M. Diehl, Th. Feldmann, H. W. Huang +1
We investigate proton mass effects in the handbag approach to wide-angle Compton scattering. We find that theoretical uncertainties due to the proton mass are significant for photo…
Spin and hard processes
P. Kroll
It is argued that spin is a fundamental aspect of gauge theories at short distances. As a consequence there are characteristic helicity asymmetries in hard inclusive and exclusive…
The two-gluon components of the eta and eta' mesons to leading-twist accuracy
Peter Kroll, Kornelija Passek-Kumericki
We critically reexamine the formalism for treating the leading-twist contributions from the two-gluon Fock components occurring in hard processes that involve eta and eta' mesons a…
GPDs, form factors and Compton scattering
P. Kroll
The basic theoretical ideas of the handbag factorization and its application to wide-angle scattering reactions are reviewed. With regard to the present experimental program carrie…
Two-Photon Annihilation into Baryon-Antibaryon Pairs
M. Diehl, P. Kroll, C. Vogt
We study the handbag contribution to two-photon annihilation into baryon-antibaryon pairs at large energy and momentum transfer. We derive factorization of the process amplitude in…
