Exclusive photoproduction of a di-meson pair with large invariant mass

Saad Nabeebaccus, David Perez, Lech Szymanowski +1

The exclusive photoproduction of a pair of light mesons is studied within the framework of collinear factorisation. The amplitude factorises into a process-dependent perturbatively…

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^…

Exclusive photoproduction of a pair in the saturation framework

Michael Fucilla, Saad Nabeebaccus, Lech Szymanowski +2

We consider the exclusive photoproduction of a pair with large invariant mass, as a promising channel to study the effects of gluon saturation. It has recently been demon…

Exclusive photoproduction of a di-meson pair with large invariant mass

Saad Nabeebaccus, David Perez, Lech Szymanowski +1

We consider the exclusive photoproduction of a di-meson pair with large invariant mass, , in the framework of collinear factorisation. The mesons conside…

Accessing Generalized Parton Distributions through exclusive processes

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

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

Complete 1-loop study of exclusive and photoproduction with full GPD evolution

Chris Flett, Jean-Philippe Lansberg, Saad Nabeebaccus +3

We discuss the exclusive photoproduction of a heavy vector quarkonium, namely and at 1-loop in . In collinear factorisation (CF), the amplitude for such a process…
