Probing non-perturbative QCD through hadronic matrix elements extracted from exclusive hard processes
B. Pire, L. Szymanowski
QCD is the theory of strong interactions and non-perturbative methods have been developed to address the confinement property of QCD. Many experimental measurements probe the confi…
On the physical Relevance of the Study of gamma* gamma -> pi0 pi0 at small t and large Q2
J. P. Lansberg, B. Pire, L. Szymanowski
We discuss the relevance of a dedicated measurement of exclusive production of a pair of neutral pions in a hard gamma* gamma scattering at small momentum transfer. In this case, t…
Probing the nucleon's transversity and the photon's distribution amplitude in lepton pair photoproduction
B. Pire, L. Szymanowski
We describe a new way to access the chiral odd transversity parton distribution in the proton through the photoproduction of lepton pairs. The basic ingredient is the interference…
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…
