Hard production of exotic hybrid mesons
I. Anikin, B. Pire, L. Szymanowski +2
Exotic hybrid mesons H, with quantum numbers J^{PC}= 1^{- +} may be copiously produced in the hard exclusive processes gamma^*(Q^2) gamma -> H and gamma^*(Q^2) P(p) -> H P(p') beca…
Born order study of gamma*gamma* -> rho rho at very high energy
B. Pire, L. Szymanowski, S. Wallon
We calculate the cross-section for the diffractive exclusive process gamma*_L (Q_1^2) gamma*_L(Q_2^2) -> rho^0_L rho^0_L, in view of its study in the future high energy e+e- linear…
Exclusive Electroproduction of Pentaquarks
M. Diehl, B. Pire, L. Szymanowski
Exclusive electroproduction of a K or K^* meson on the nucleon can give a Theta^+ pentaquark in the final state. This reaction offers an opportunity to investigate the structure of…
Pomeron/Odderon Interference in Diffractive Meson Pairs Production
P. Hagler, B. Pire, L. Szymanowski +1
We study Pomeron-Odderon interference effects giving rise to charge and single-spin asymmetries in diffractive electroproduction of a pair. The final state interactions a…
Diffractive electroproduction of two mesons separated by a large rapidity gap
D. Yu. Ivanov, B. Pire, L. Szymanowski +1
We consider the process gamma^* N -> M_1 M_2 N' with a large rapidity gap between the two mesons M_1 and M_2. Within the QCD collinear approximation, the scattering amplitude may b…
