Abstract

We study the form factors of the η c meson in the light-front quark model. We explicitly show that the transition form factor of η c →γ ∗ γ as a function of the momentum transfer is consistent with the experimental data by the BaBar collaboration, while the decay constant of η c is found to be \(f_{\eta_{c}}=230.5^{+52.2}_{-61.0}\) and \(303.6^{+115.2}_{-116.4}~\mathrm{MeV}\) for \(\eta_{c}\sim c\bar{c}\) by using two η c →γγ decay widths of 5.3±0.5 and 7.2±2.1 keV, given by Particle Data Group and Lattice QCD calculation, respectively.
