${\eta }_c$ 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 (${\eta }_c(1S)$) channel, we calculate the elastic (EFF) and transition form factors (TFF) ($η_c(1S) \rightarr…
