Electromagnetic form factors of heavy-light pseudoscalar mesons

A. S. Miramontes, J. Papavassiliou, J. M. Pawlowski

Abstract

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-dependent Bethe-Salpeter framework.
