Accessing pion GPDs through the Sullivan process: is it feasible?
Morgado Chávez, José Manuel; Bertone, Valerio; Defurne, Maxime; Soto, Feliciano de; Mezrag, Cédric; Moutarde, Hervé; Rodríguez Quintero, José
; Segovia, Jorge (Sociedad Mexicana de Física, 2022)
Describing 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 ... -
Accessing the Pion 3D Structure at US and China Electron-Ion Colliders
Morgado Chávez, José Manuel; Bertone, Valerio; Soto Borrero, Feliciano Carlos de; Defurne, Maxime; Mezrag, Cédric; Moutarde, Hervé; Rodríguez Quintero, José; Segovia, Jorge (American Physical Society, 2022-05)
We present the first systematic feasibility study of accessing generalized parton distributions of the pion at an electron-ion collider through deeply virtual Compton scattering. Relying on state-of-the-art models for ... -
Concerning pion parton distributions
Cui, Zhu-Fang; Ding, M.; Morgado Chávez, José Manuel; Raya, Khépani; Binosi, Daniele; Chang, L.; Papavassiliou, J.; Roberts, Craig D.; Rodríguez Quintero, José; Schmidt, S. M. (Springer, 2022-01)
Analyses of the pion valence-quark distribution function (DF), uπ (x; ζ ), which explicitly incorporate the behaviour of the pion wave function prescribed by quantum chromodynamics (QCD), predict uπ (x 1; ζ ) ∼ (1 − ... -
Emergence of pion parton distributions
Cui, Zhu-Fang; Ding, M.; Morgado Chávez, José Manuel; Raya, Khépani; Binosi, Daniele; Chang, L.; Soto, F. de; Roberts, Craig D.; Rodríguez Quintero, José; Schmidt, S. M. (American Physical Society, 2022-05)
Supposing only that there is an effective charge which defines an evolution scheme for parton distribution functions (DFs) that is all-orders exact, strict lower and upper bounds on all Mellin moments of the valence-quark ... -
Generalized parton distributions of the pion: modeling, evolution and observable implications
(Universidad de Huelva, 2022)Yet the Standard Model of particle physics is so far the most successful theory ever conceived in science, with countless of achievements in the description of Nature; still a number of phenomena remains to be properly ... -
Pion generalized parton distributions: A path toward phenomenology
Morgado Chávez, José Manuel; Bertone, Valerio; Soto Borrero, Feliciano Carlos de; Defurne, Maxime; Mezrag, Cédric; Moutarde, Hervé; Rodríguez Quintero, José; Segovia, Jorge (American Physical Society, 2022-05)
We introduce a new family of generalized parton distribution models able to fulfill by construction all the theoretical properties imposed by QCD. These models are built on standard parton distribution functions and ... -
Pion GPDs: Constraints, modelling and experimental access
(SciPost Foundation, 2021-04)The study of Generalised Parton Distributions is a hot-topic in hadron physics. Due to its connection with chiral symmetry breaking, assessing those of pions is of great inter- est. For this reason, we present a novel ... -
Revealing pion and kaon structure via generalised parton distributions
Raya, Khépani; Cui, Zhu-Fang; Chang, L.; Morgado Chávez, José Manuel; Roberts, Craig D.; Rodríguez Quintero, José (IOP Publishing, 2022-01)
Clear windows onto emergent hadron mass (EHM) and modulations thereof by Higgs boson interactions are provided by observable measures of pion and kaon structure, many of which are accessible via generalised parton distributions ... -
Revisiting evolution equations for generalised parton distributions
(Springer Open, 2022)We revisit the evolution of generalised parton distributions (GPDs) in momentum space. We formulate the evolution kernels at one loop in perturbative quantum chromodynamics (pQCD) in a form that is suitable for numerical ...
