DVCS off deuteron and twist three contributions
I. V. Anikin, R. S. Pasechnik, B. Pire +1
We study the deeply virtual Compton scattering off a spin-one particle, which is exemplified by the case of coherent scattering on a deuteron target. We discuss the role of twist t…
Exclusive electroproduction of rhoT meson with twist three accuracy
I. V. Anikin, D. Yu. Ivanov, B. Pire +2
Exclusive electroproduction of vector mesons is a crucial way to probe QCD factorization properties. Such a factorization is up to now only proven, at the twist 2 level, for a long…
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…
Photon-photon collision: ambiguity and duality in QCD factorization theorem
I. V. Anikin, I. O. Cherednikov, N. G. Stefanis +1
We discuss duality in ``two-photon''-like processes in the scalar model and also in the process in QCD. Duality implies the equivalence between two distinct non…
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…
gamma* -> rhoT impact factor with twist three accuracy
I. V. Anikin, D. Yu. Ivanov, B. Pire +2
We evaluate the impact factor of the transition gamma* -> rhoT taking into account the twist 3 contributions. We show that a gauge invariant expression is obtained with the help of…
