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…
Pion and kaon electromagnetic and gravitational form factors
Yin-Zhen Xu, Minghui Ding, Khépani Raya +3
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…
An algebraic model to study the internal structure of pseudo-scalar mesons with heavy-light quark content
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…
Light-front Wave Functions of Vector Mesons in an Algebraic Model
B. Almeida-Zamora, J. J. Cobos-Martínez, A. Bashir +3
Inspired by the recent development of an algebraic model which provides an adequate and unified description of the internal structure of the lowest-lying pseudo-scalar mesons, belo…
Empirical Determination of the Pion Mass Distribution
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…
Highlights of pion and kaon structure from continuum analyses
Khépani Raya, José Rodríguez-Quintero
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…
Proton and pion distribution functions in counterpoint
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…
Concerning pion parton distributions
Z. -F. Cui, M. Ding, J. M. Morgado +7
Analyses of the pion valence-quark distribution function (DF), , which explicitly incorporate the behaviour of the pion wave function prescribed by quantum chromodynami…
Pion GPDs: A path toward phenomenology
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…
Measures of pion and kaon structure from generalised parton distributions
Jin-Li Zhang, Khépani Raya, Lei Chang +4
Pion and kaon structural properties provide insights into the emergence of mass within the Standard Model and attendant modulations by the Higgs boson. Novel expressions of these e…
QCD2019 Workshop Summary
S. J. Brodsky, V. D. Burkert, D. S. Carman +26
The topical workshop {\it Strong QCD from Hadron Structure Experiments} took place at Jefferson Lab from Nov. 6-9, 2019. Impressive progress in relating hadron structure observable…
Effective charge from lattice QCD
Zhu-Fang Cui, Jin-Li Zhang, Daniele Binosi +7
Using lattice configurations for quantum chromodynamics (QCD) generated with three domain-wall fermions at a physical pion mass, we obtain a parameter-free prediction of QCD's reno…
QCD: Restoration of Chiral Symmetry and Deconfinement for Large N_f
A. Bashir, A. Raya, J. Rodríguez-Quintero
Exploiting the recent lattice results for the infrared gluon propagator with light dynamical quarks, we solve the gap equation for the quark propagator. We thus model the chiral sy…
