Unraveling Generalized Parton Distributions Through Lorentz Symmetry and Partial DGLAP Knowledge
P. Dall'Olio, F. De Soto, C. Mezrag +5
Relying on the polynomiality property of generalized parton distributions, which roots on Lorentz covariance, we prove that it is enough to know them at vanishing- and low-skewness…

A unified set of predictions for pion and kaon elastic electromagnetic and gravitational form factors is obtained using a symmetry-preserving truncation of each relevant quantum fi…
Pion distribution functions from low-order Mellin moments
Ya Lu, Yin-Zhen Xu, Khépani Raya +2
Exploiting an evolution scheme for parton distribution functions (DFs) that is all-orders exact, contemporary lattice-QCD (lQCD) results for low-order Mellin moments of the pion va…

B. Almeida-Zamora, J. J. Cobos-Martínez, A. Bashir +3
The internal structure of all lowest-lying pseudo-scalar mesons with heavy-light quark content is studied in detail using an algebraic model that has been applied recently, and suc…

A. Accardi, P. Achenbach, D. Adhikari +441
This document presents the initial scientific case for upgrading the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (JLab) to 22 GeV. It is the result of a…

Yin-Zhen Xu, Khépani Raya, Zhu-Fang Cui +2
Existing pion+nucleus Drell-Yan and electron+pion scattering data are used to develop ensembles of model-independent representations of the pion generalised parton distribution (GP…
General kinematics of the three-gluon vertex from quenched lattice QCD
Fernando Pinto-Gómez, Feliciano de Soto, Mauricio N. Ferreira +2
We present new results for the transversely projected three-gluon vertex from quenched lattice QCD simulations using standard Wilson action. While previous works focused in some pa…
Highlights of pion and kaon structure from continuum analyses

One of the biggest challenges in contemporary physics is understanding the origin and dynamics of the internal structure of hadrons which, at a fundamental level, is described by q…

Ya Lu, Lei Chang, Khépani Raya +2
Working with proton and pion valence distribution functions (DFs) determined consistently at the same, unique hadron scale and exploiting the possibility that there is an effective…

José Manuel Morgado Chavez, Valerio Bertone, Feliciano De Soto Borrero +5
We introduce a new family of Generalised Parton Distribution models able to fulfil by construction all the theoretical properties imposed by QCD. These models are built on standard…
Reconstructing QCD Spectral Functions with Gaussian Processes
Jan Horak, Jan M. Pawlowski, José Rodríguez-Quintero +4
We reconstruct ghost and gluon spectral functions in 2+1 flavor QCD with Gaussian process regression. This framework allows us to largely suppress spurious oscillations and other c…
Linking continuum and lattice quark mass functions via an effective charge
