Electromagnetic form factors of heavy-light pseudoscalar mesons
A. S. Miramontes, J. Papavassiliou, J. M. Pawlowski
We report calculations of space-like electromagnetic form factors and charge radii of pseudoscalar mesons, covering both light and heavy-light flavour sectors within a flavour-depe…
Cosmology from asymptotically safe Proca theories
Carlos Pastor-Marcos, Lavinia Heisenberg, Ãlvaro Pastor-Gutiérrez +2
Effective field theories for cosmology offer a powerful framework to investigate the dynamics of space--time and address longstanding open puzzles. In this work, we initiate a prog…
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…
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…
