Contribution of neutral pseudoscalar mesons to within a Schwinger-Dyson equations approach to QCD
K. Raya, A. Bashir, P. Roig
A continuum approach to Quantum Chromodynamics (QCD), based upon Schwinger-Dyson (SD) and Bethe-Salpeter (BS) equations, is employed to provide a tightly constrained prediction for…

Elastic and Transition Form Factors: Contact Interaction and Algebraic Model
Marco A. Bedolla, Khépani Raya, J. J. Cobos-Martínez +1
For the flavor-singlet heavy quark system of charmonia in the pseudoscalar () channel, we calculate the elastic (EFF) and transition form factors (TFF) ($η_c(1S) \rightarr…
