Extraction of DVCS amplitudes off the nucleon
C. Mezrag, P. Sznajder, J. Wagner
This work presents a modern extraction of deeply virtual Compton scattering (DVCS) amplitudes off the proton and off the neutron through a global analysis of experimental data. The…
Exclusive Quark and Gluon Dijet Production as Probes of GPDs at Collider Energies
Zhuoyi Pang, Paweł Sznajder, Lech Szymanowski +1
We study exclusive electroproduction of dijets in the collinear factorization framework as a probe of generalized parton distributions (GPDs). For quark dijet production, we extend…
Quark and gluon tomography of the helium-4 nucleus
V. Martínez-Fernández, B. Pire, P. Sznajder +1
QCD collinear factorization allows coherent hard exclusive reactions to reveal the quark-gluon structure of light nuclei, enabling their 3D tomography. We study elastic form factor…
Coherent deeply virtual Compton scattering on helium-4 beyond leading power
Víctor Martínez-Fernández, B. Pire, P. Sznajder +1
Coherent hard exclusive reactions on light nuclei provide access to their quark and gluon structure and enable three-dimensional tomography of these complex systems. We study deepl…
Electro- and photoproduction of muon pairs with CLAS12: Double Deeply Virtual Compton Scattering, Timelike Compton Scattering, and production
J. S. Alvarado, N. Baltzell, M. Bondi +98
The CEBAF Large Acceptance Spectrometer for operation at 12 GeV (CLAS12) at the Thomas Jefferson National Accelerator Facility has played a central role in advancing the understand…
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…
A Unified Neural-Network Framework for Nucleon Imaging from Numerical Simulations of QCD
Min-Huan Chu, Krzysztof Cichy, Martha Constantinou +2
Parton distributions encode the momentum-space structure and, in their generalizations, the spatial tomography of quarks and gluons inside hadrons, the building blocks of visible m…
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 is…
Nucleon tomography and total angular momentum of valence quarks from synergy between lattice QCD and elastic scattering data
Krzysztof Cichy, Martha Constantinou, Paweł Sznajder +1
We present an exploratory work on integrating lattice-QCD results with experimental data for elastic scattering. Within the framework of generalized parton distributions (GPDs), th…
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…
Results of the 2022 ECFA Early-Career Researchers Panel survey on career prospects and diversity
Julia Allen, Kamil Augsten, Giovanni Benato +18
This document presents the outcomes of a comprehensive survey conducted among early career researchers (ECRs) in academic particle physics. Running from September 24, 2022, to Marc…
