Hard diffractive processes and non-perturbative matrix elements beyond leading twist: rhoT-meson production
I. V. Anikin, D. Yu. Ivanov, B. Pire +2
Within the kt-factorization approach, we evaluate the impact factor of the transition gamma* -> rhoT taking into account the twist 3 contributions. We show that a gauge invariant e…
Looking for the Odderon in photon collisions
Bernard Pire, Florian Schwennsen, Lech Szymanowski +1
We discuss the production of two pion pairs in photon collisions at high energies. We calculate the according matrix elements in k_T-factorization and discuss the possibility to re…
Pomeron Odderon interference in production of pi+ pi- pairs at LHC
B. Pire, F. Schwennsen, L. Szymanowski +1
We discuss the production of two pion pairs in photon collisions at high energies as it can take place in ultraperipheral collisions at hadron colliders such as the LHC. We calcula…
QCD factorization beyond leading twist in exclusive rho(T) meson production
I. V. Anikin, D. Yu. Ivanov, B. Pire +2
We describe hard exclusive processes involving a transversally polarized rho meson in the twist 3 approximation, in a framework based on the Taylor expansion of the amplitude aroun…
Probing photon structure in DVCS on a photon target
M. El Beiyad, S. Friot, B. Pire +2
The factorization of the amplitude for the deeply virtual Compton scattering (DVCS) process gamma*(Q) gamma -> gamma gamma at high Q2 is demonstrated in two distinct kinematical do…
