Semiexclusive production of mesons in proton-proton collisions with electromagnetic and diffractive dissociation of one of the protons
Anna Cisek, Wolfgang Schäfer, Antoni Szczurek
We calculate the cross sections for both electromagnetic and diffractive dissociation of protons for semiexclusive production of mesons in proton-proton collisions at the LHC…
Photoproduction of and states in exclusive and proton-dissociative diffractive events
Wolfgang Schäfer, Antoni Szczurek, Anna Cisek
The amplitude for , where is a or ground state or excited vector meson, is calculated in a pQCD -factorization approach. We use this amplitude to p…
Diffractive production of quark-antiquark pairs
Antoni Szczurek, Marta Luszczak, Wolfgang Schafer
We discuss diffractive dissociation of gluons into heavy quark pairs. The particular mechanism is similar to the diffractive dissociation of virtual photons into quarks. The amplit…
Exclusive production of meson in proton-proton collisions at high energies
Anna Cisek, Piotr. Lebiedowicz, Wolfgang Schäfer +1
First we calculate cross section for the reaction from the threshold to very large energies. At low energies the pion exchange is the dominant mechanism. At large energ…
Unitarity cutting rules for hard processes on nuclei
W. Schäfer
Heavy nuclei introduce a new scale into the pQCD description of hard processes on nuclei, the saturation scale, and the familiar linear k_\perp-factorization breaks down. It is rep…
