Distribution Amplitudes of Heavy-Light Mesons
Daniele Binosi, Lei Chang, Minghui Ding +3
A symmetry-preserving approach to the continuum bound-state problem in quantum field theory is used to calculate the masses, leptonic decay constants and light-front distribution a…
Nucleon Parton Distribution Amplitude: A scalar diquark picture
Cédric Mezrag, Jorge Segovia, Minghui Ding +2
We report progress on the development of Perturbative Integral Representation Ansätze to compute the nucleon Faddeev Wave function, using an explicit quark-diquark picture. Our for…
Nucleon-to-Roper electromagnetic transition form factors at large-
Chen Chen, Ya Lu, Daniele Binosi +3
High-precision nucleon-resonance electroproduction data on a large kinematic domain of energy and momentum transfer have proven crucial in revealing novel features of strong intera…
transition form factors
Minghui Ding, Khepani Raya, Adnan Bashir +4
Using a continuum approach to the hadron bound-state problem, we calculate transition form factors on the entire domain of spacelike momenta, for comparis…
Mass-dependence of pseudoscalar meson elastic form factors
Muyang Chen, Minghui Ding, Lei Chang +1
A continuum approach to quark-antiquark bound-states is used to determine the electromagnetic form factors of pion-like mesons with masses , , ,…
Proton tensor charges from a Poincaré-covariant Faddeev equation
Qing-Wu Wang, Si-Xue Qin, Craig D. Roberts +1
The proton's tensor charges are calculated at leading order in a symmetry-preserving truncation of all matter-sector equations relevant to the associated bound-state and scattering…
New Perspective on Hybrid Mesons
Shu-Sheng Xu, Zhu-Fang Cui, Lei Chang +3
It is thought that strong interactions within the Standard Model can generate bound-states in which non-Abelian gauge-bosons play a dual role, serving both as force and matter fiel…
Pion and kaon valence-quark quasiparton distributions
Shu-Sheng Xu, Lei Chang, Craig D. Roberts +1
Algebraic Ansaetze for the Poincaré-covariant Bethe-Salpeter wave functions of the pion and kaon are used to calculate their light-front wave functions (LFWFs), parton distribution…
Process-independent effective coupling. From QCD Green's functions to phenomenology
Jose Rodríguez-Quintero, Daniele Binosi, Cédric Mezrag +2
This article reports on a very recent proposal for a new type of process-independent QCD effective charge [Phys.Rev.D96(2017)054026] defined, as an anologue of the Gell-Mann-Low ef…
Poincaré-covariant analysis of heavy-quark baryons
Si-Xue Qin, Craig D. Roberts, Sebastian M. Schmidt
We use a symmetry-preserving truncation of meson and baryon bound-state equations in quantum field theory in order to develop a unified description of systems constituted from ligh…
N* Structure and Strong QCD
Craig D. Roberts
In attempting to match QCD with Nature, it is necessary to confront the many complexities of strong, nonlinear dynamics in relativistic quantum field theory, e.g. the loss of parti…
Nucleon viewed as a Borromean Bound-State
Jorge Segovia, Cédric Mezrag, Lei Chang +1
We explain how the emergent phenomenon of dynamical chiral symmetry breaking ensures that Poincaré covariant analyses of the three valence-quark scattering problem in continuum qua…
