Real poles with opposite-sign residues in the non-perturbative quark propagator
R. Alkofer, M. N. Ferreira, A. S. Miramontes +2
We investigate the analytic structure of the quark propagator in the Landau gauge by dynamically coupling the standard gap equation to the non-perturbative quark-gluon vertex. Empl…
Quark-gluon vertex in the complex plane
M. N. Ferreira, A. S. Miramontes, J. M. Morgado +1
In the present work we explore for the first time the general structure and properties of the nonperturbative quark-gluon vertex in the complex plane. Specifically, we focus on the…
Light mesons in the symmetric-vertex approximation
M. N. Ferreira, A. S. Miramontes, J. M. Morgado +1
We compute the spectrum of light mesons, composed by up, down, and strange quarks, using a symmetry-preserving approximation that permits the inclusion of fully-dressed quark-gluon…
Pions reloaded
M. N. Ferreira, A. S. Miramontes, J. M. Morgado +2
We present a novel version of the pion Bethe-Salpeter equation in the chiral limit, solved using as ingredients state-of-the-art QCD correlation functions. The constraints imposed…
Baryonic form factors of light pseudoscalar mesons
A. S. Miramontes, J. M. Morgado, J. Papavassiliou
Employing the Bethe-Salpeter formalism, we present a computation of the space-like baryonic form factor for the pion and kaon. In the exact isospin-symmetric limit this observable…
Revisiting evolution equations for generalised parton distributions
Valerio Bertone, Hervé Dutrieux, Cédric Mezrag +2
We revisit the evolution of generalised parton distributions (GPDs) in momentum space. We formulate the evolution kernels at one-loop in perturbative QCD (pQCD) in a form suitable…
Emergence of pion parton distributions
Z. -F. Cui, M. Ding, J. M. Morgado +7
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 o…
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…
Revealing pion and kaon structure via generalised parton distributions
Khepani Raya, Zhu-Fang Cui, Lei Chang +3
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…
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…
