Two-photon annihilation into octet meson pairs: symmetry relations in the handbag approach
Markus Diehl, Peter Kroll
We explore the implications of SU(3) flavor symmetry in the soft handbag mechanism for two-photon annihilation into pairs of pseudoscalar octet mesons. In this approach we obtain a…
Transversity in exclusive meson electroproduction
P. Kroll
In this talk various spin effects in hard exclusive electroproduction of mesons are briefly reviewed and the data discussed in the light of recent theoretical calculations within t…

An attempt to understand exclusive pi+ electroproduction
S. V. Goloskokov, P. Kroll
Hard exclusive pi+ electroproduction is investigated within the handbag approach. The prominent role of the pion-pole contribution is demonstrated. It is also shown that the experi…
Proton-Antiproton Annihilation into a Lambda_c-Antilambda_c Pair
A. T. Goritschnig, P. Kroll, W. Schweiger
The process p-pbar -> Lambda_c-Antilambda_c is investigated within the handbag approach. It is shown that the dominant dynamical mechanism, characterized by the partonic subprocess…
within a Handbag Picture -- Cross Section and Spin Observables
A. T. Goritschnig, P. Kroll, W. Schweiger
We study the process within the generalized parton picture. Our starting point is the double handbag diagram which factorizes into soft generalized parto…
