Added Prognostic Value of EEG Reactivity in Comatose Patients Following Cardiac Arrest. [PDF]
Ann Clin Transl NeurolABSTRACT Objectives To evaluate the added prognostic value of EEG reactivity for favorable outcome compared with background analysis during and after targeted temperature management (TTM). Methods Prospective observational cohort study of comatose post–cardiac arrest patients admitted to a single academic center between 2017 and 2022, all undergoing ...

Helicity-dependent generalized parton distributions for nonzero skewness
European Physical Journal C: Particles and Fields, 2017 We investigate the helicity-dependent generalized parton distributions (GPDs) in momentum as well as transverse position (impact) spaces for the u and d quarks in a proton when the momentum transfer in both the transverse and the longitudinal directions ...

Generalized parton distributions through universal moment parameterization: non-zero skewness case
Journal of High Energy Physics, 2023 We present the first global analysis of generalized parton distributions (GPDs) combing lattice quantum chromodynamics (QCD) calculations and experiment measurements including global parton distribution functions (PDFs), form factors (FFs) and deeply ...

On the equivalence of GPD representations
EPJ Web of Conferences, 2016 Phenomenological representations of generalized parton distributions (GPDs) implementing the non-trivial field theoretical requirements are employed in the present day strategies for extracting of hadron structure information encoded in GPDs from the ...

Generalized parton distributions through universal moment parameterization: zero skewness case
Journal of High Energy Physics, 2022 We present a global analysis program for the generalized parton distributions (GPDs) based on conformal moment expansion. We apply the strategy of universal moment parameterization to fit both the collinear parton distribution functions (PDFs) from ...

Transition GPDs and exclusive electroproduction of $\pi-\Delta(1232)$ final states [PDF]
, 2022 We investigate exclusive electroproduction of $\pi^-\Delta^{++}$ within the handbag approach in which the helicity amplitudes factorize into generalized parton distributions (GPDs) and hard partonic subprocesses.

Artificial neural network modelling of generalised parton distributions
European Physical Journal C: Particles and Fields, 2022 We discuss the use of machine learning techniques in effectively nonparametric modelling of generalised parton distributions (GPDs) in view of their future extraction from experimental data.

Accessing pion GPDs through the Sullivan process: is it feasible? [PDF]
, 2021 International audienceDescribing hadronic structure is one of the most intriguing problems in physics. In this respect, generalized parton distributions (GPDs) constitute an outstanding tool, allowing to draw “three dimensional pictures” of hadron’s ...

Probing GPDs in photoproduction processes at hadron colliders
, 2015 International audienceGeneralized parton distributions (GPDs) enter QCD factorization theorems for hard exclusive reactions. They encode rich information about hadron partonic structure.

Journal of High Energy Physics, 2022 We show that exclusive production of a pair of high transverse momentum photons in pion-nucleon collisions can be systematically studied in QCD factorization approach if the photon’s transverse momentum q T with respect to the colliding pion is much ...
