Wide-angle pion-Delta(1232) photoproduction
P. Kroll
High-energy wide-angle photoproduction of pion-Delta final states is investigated within the handbag mechanism to twist-3 accuracy. In this approach the process amplitudes factoriz…
Twist-3 contributions to wide-angle photoproduction of pions
P. Kroll, K. Passek-Kumericki
We investigate wide-angle pi^0 photoproduction within the handbag approach to twist-3 accuracy. In contrast to earlier work both the 2-particle as well as the 3-particle twist-3 co…
Signatures of the handbag mechanism in wide-angle photoproduction of pseudoscalar mesons
H. W. Huang, R. Jakob, P. Kroll +1
Wide-angle photoproduction of pseudoscalar mesons is investigated under the assumption of dominance of the handbag mechanism considering both quark helicity flip and non-flip. The…
Large momentum transfer electroproduction of mesons
H. W. Huang, P. Kroll
Assuming the proton's light-cone wave function to be dominated by small parton virtualities and small intrinsic transverse momenta, we show that the electroproduction amplitudes at…
Colour-octet contributions to exclusive charmonium decays
J. Bolz, P. Kroll, G. A. Schuler
We investigate the theoretical uncertainties of -wave charmonium decays into two pions, , . Constraining the pion distribution-amplitude from…
