Hadronic vacuum polarization contribution to from functional methods with strong and electromagnetic isospin breaking
Angel S. Miramontes, Adnan Bashir, Christian S. Fischer +1
The paper calculates the leading-order hadronic vacuum‑polarization contribution to the muon's anomalous magnetic moment using continuum QCD methods (Dyson‑Schwinger and Bethe‑Salp…
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…
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…
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…
