Next-to-next-to-leading order QCD corrections to pion (kaon)-induced exclusive Drell-Yan process
Yu Jia, Bernard Pire, Qin-Tao Song +2
The high-energy pion and kaon beams proposed for future experiments at J-PARC offer a unique opportunity to investigate exclusive Drell-Yan processes induced by pions or kaons, whi…
2025 EIC-France Workshop: Physics Highlights and Perspectives
F. Arleo, V. Bertone, J. Bettane +75
This document presents a synthesis of the theory contributions and discussions from the 2nd EIC-France Workshop, held at IJCLab (Orsay) on 1-3 December 2025. The workshop brought t…
Hard exclusive photoproduction of photon-meson pairs: pseudoscalar channels , and
Nikola Crnković, Goran Duplančić, Saad Nabeebaccus +4
We investigate the hard exclusive photoproduction of photon-meson pairs at leading-twist and leading-order in perturbative QCD, and focus on pseudoscalar mesons $\text{M} \in \{π^\…
Accessing baryon-antibaryon generalized distribution amplitudes in
Jing Han, Bernard Pire, Qin-Tao Song
is the golden process to access chiral-even di-baryon generalized distribution amplitudes (GDAs) as deeply virtual Compton scattering has proven to be for the…
Improved phenomenology of transition distribution amplitudes
Bernard Pire, Kirill Semenov-Tian-Shansky, Paweł Sznajder +1
To study cross sections and polarization asymmetries for the processes and in the backward region, we develop a flexible phenomenological model…
Revealing chiral-odd two-meson generalized distribution amplitudes in reactions
Shohini Bhattacharya, Renaud Boussarie, Bernard Pire +1
We demonstrate that chiral-odd dimeson generalized distribution amplitudes (CO-GDAs) -- nonperturbative objects encoding the transition of a quark-antiquark pair into two mesons --…
