Transversity Generalized Parton Distributions from gamma N -> pi rhot N' with a Large pi rhot Invariant Mass
M. El Beiyad, B. Pire, M. Segond +2
The chiral-odd transversity generalized parton distributions of the nucleon can be accessed experimentally through the exclusive photoproduction process gamma N -> pi rhoT N', with…
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…
QCD factorization of exclusive processes beyond leading twist: gamma*T -> rhoT impact factor with twist three accuracy
I. V. Anikin, D. Yu. Ivanov, B. Pire +2
We describe a consistent approach to factorization of scattering amplitudes for exclusive processes beyond the leading twist approximation. The method involves the Taylor expansion…
QCD factorization beyond leading twist in exclusive processes: rhoT-meson production
I. V. Anikin, D. Yu. Ivanov, B. Pire +2
Exclusive processes in hard electroproduction is one of the best place for understanding the factorization properties of QCD. The HERA experiment recently provided precise data for…
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…

I. V. Anikin, D. Yu. Ivanov, B. Pire +2
We describe hard exclusive processes beyond the leading twist approximation in a framework based on the Taylor expansion of the amplitude around the dominant light-cone directions.…
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…
