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…

Some forgotten features of the Bose Einstein Correlations

G. A. Kozlov, O. V. Utyuzh, G. Wilk +1

Notwithstanding the visible maturity of the subject of Bose-Einstein Correlations (BEC), as witnessed nowadays, we would like to bring to ones attention two points, which apparentl…

Production of a pion in association with a high-Q2 dilepton pair in antiproton-proton annihilation at GSI-FAIR

J. P. Lansberg, B. Pire, L. Szymanowski

We evaluate the cross section for anti-p p -> l+ l- pi0 in the forward direction and for large lepton pair invariant mass. In this kinematical region, the leading-twist amplitude f…

Diffractive production of two rho^0_L mesons in e^+e^- collisions

M. Segond, L. Szymanowski, S. Wallon

We present an estimate of the cross-section for the exclusive production of a rho_L^0-meson pair in e^+e^- scattering, which will be studied in the future high energy International…

Exclusive J/psi and Upsilon hadroproduction and the QCD odderon

A. Bzdak, L. Motyka, L. Szymanowski +1

We study pp and p\bar p collisions which lead to the exclusive production of J/psi or Upsilon from the pomeron-odderon and the pomeron-photon fusion. We calculate scattering amplit…
