Hadronic vacuum polarization contribution to from functional methods with strong and electromagnetic isospin breaking
Angel S. Miramontes, Adnan Bashir, Christian S. Fischer +1
We present a continuum-QCD determination of the leading-order hadronic vacuum-polarization contribution to the anomalous magnetic moment of the muon within the Dyson-Schwinger and…
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…
Pion physics with dressed quark-gluon vertices
Mauricio N. Ferreira, Angel S. Miramontes, Jose M. Morgado +2
Recently, a theoretical framework was set up in [1], which allows for the symmetry-preserving inclusion of full quark-gluon vertices in the description of the meson dynamics. In th…
Electromagnetic properties of heavy-light mesons

The form factor for the anomalous process is calculated in the isospin limit for several values of the light current-quark mass (i.e., the…
Heavy-light mesons from a flavour-dependent interaction
Fei Gao, Angel S. Miramontes, Joannis Papavassiliou +1
We introduce a new symmetry-preserving framework for the physics of heavy-light mesons, whose key element is the effective incorporation of flavour-dependent contributions into the…

We present a calculation for the masses of the first radially excited states of forty mesons and diquarks made up of and quarks, including states that contain one or…
Strong Interaction Physics at the Luminosity Frontier with 22 GeV Electrons at Jefferson Lab
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…
