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…
Can one measure timelike Compton scattering at LHC ?
B. Pire, L. Szymanowski, J. Wagner
Exclusive photoproduction of dileptons, gamma N->e+e-N, is and will be measured in ultraperipheral collisions at hadron colliders, such as the Tevatron, RHIC and the LHC . We demon…
Pomeron-Odderon interference in production of pi^ + pi^- pairs in ultraperipheral collisions
B. Pire, L. Szymanowski, F. Schwennsen +1
In this contribution we discuss the production of two pion pairs in high energy photon collisions as they can be produced in ultraperipheral collisions at hadron colliders such as…
Hard Pomeron-Odderon interference effects in the production of pi^+pi^- pairs in high energy gamma-gamma collisions at the LHC
B. Pire, L. Szymanowski, F. Schwennsen +1
We estimate the production of two meson pairs in high energy photon photon collisions produced in ultraperipheral collisions at LHC. We show that the study of charge asymmetries ma…
Two Photon Distribution Amplitudes
M. El Beiyad, B. Pire, L. Szymanowski +1
The factorization of the amplitude of the process gamma* gamma -> gamma gamma in the low energy and high photon virtuality region is demonstrated at the Born order and in the leadi…
Diphoton Generalized Distribution Amplitudes
M. El Beiyad, B. Pire, L. Szymanowski +1
We calculate the leading order diphoton generalized distribution amplitude by calculating the amplitude of the process gamma* gamma -> gamma gamma in the low energy and high photon…
