Light meson-quark couplings and radii: ratios from one loop calculation
August 01, 2022
In this work some results for light mesons couplings to constituent quarks obtained in a one loop calculation are compared among each other in the limit of large quark effective mass. These coupling constants are extracted from momentum dependent form factors obtained in a dynamical approach from an important term of the QCD quark-effective action. For this, exact and approximated ratios of the different light meson-constituent quark coupling constants
are provided. The comparison is also done for the different light mesons and constituent quark averaged quadratic radii.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
