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…

Hard exclusive photoproduction of photon-meson pairs: pseudoscalar channels $π$ , $η$ and $η^{'}$

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 $e^{\pm} γ \to e^{\pm} B B ˉ$

Jing Han, Bernard Pire, Qin-Tao Song

$γ^{*} γ \to B B ˉ$ 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 $π N$ transition distribution amplitudes

Bernard Pire, Kirill Semenov-Tian-Shansky, Paweł Sznajder +1

To study cross sections and polarization asymmetries for the processes $e p \to e n π^{+}$ and $e p \to e p π^{0}$ in the backward region, we develop a flexible phenomenological model…

Revealing chiral-odd two-meson generalized distribution amplitudes in $e^{-} e^{+} \to (π π) (π π)$ 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 --…

Baryon-antibaryon generalized distribution amplitudes and $e^{+} e^{-} \to B B ˉ γ$

Jing Han, Bernard Pire, Qin-Tao Song

Baryon-antibaryon generalized distribution amplitudes (GDAs) give an access to timelike gravitational form factors (GFFs) which are complementary to the spacelike ones which can be…

Backward DVCS in a Sullivan process

Abigail R. Castro, Cédric Mezrag, Jose M. Morgado Chávez +1

Mesons' internal structure and dynamics may be accessed through hard exclusive electroproduction processes such as deeply virtual Compton scattering in both near forward and near b…

Accessing Generalized Parton Distributions through $2 \to 3$ exclusive processes

Goran Duplančić, Saad Nabeebaccus, Kornelija Passek-K. +3

We review our results on a new class of $2 \to 3$ exclusive processes, as a probe of both chiral-even and chiral-odd quark GPDs. We consider the exclusive photoproduction of a phot…

Double DVCS amplitudes including kinematic twist-3 and 4 corrections

V. Martinez-Fernandez, B. Pire, P. Sznajder +1

Generalized parton distributions (GPDs) are off-forward matrix elements of quark and gluon operators that work as a window to the total angular momentum of partons and their transv…

Exclusive photoproduction of a photon-meson pair: A new class of observables to probe GPDs

Goran Duplančić, Saad Nabeebaccus, Kornelija Passek-K. +4

We discuss the exclusive photoproduction of a photon-meson pair with large $p_{T}$ as a channel to probe generalised parton distributions (GPDs). Like other $2 \to 3$ exclusive p…

Kinematical higher-twist corrections in $γ^{*} \to M_{1} M_{2} γ$ : Charged meson production

Bernard Pire, Qin-Tao Song

Generalized distribution amplitudes (GDAs) of mesons can be probed by the reactions $e^{-} e^{+} \to M_{1} M_{2} γ$ , which are accessible at electron-positron colliders such as BESIII and…
