Elucidating the effect of intermediate resonances in the quark interaction kernel on the time-like electromagnetic pion form factor
Ángel S. Miramontes López, Hèlios Sanchis-Alepuz, Reinhard Alkofer
An exploratory study of the time-like pion electromagnetic form factor in a Poincaré-covariant bound state formalism in the isospin symmetric limit is presented. Starting from a qu…

On the effect of resonances in the quark-photon vertex
Ángel S. Miramontes, Hèlios Sanchis-Alepuz
A calculation of hadronic timelike form factors in the Poincaré-covariant Bethe-Salpeter formalism necessitates knowing the analytic structure of the non-perturbative quark-photon…

Decay mechanisms in bound state interaction kernels
A. S. Miramontes, H. Sanchis-Alepuz
We present progress on the study of decay-channel effects in the properties of hadrons using covariant Bethe-Salpeter equations (BSEs). The main goal will be to develop BSE kernels…
