The ${\eta }_c$-meson leading-twist distribution amplitude

Benoît Blossier, Mariane Mangin-Brinet, José Manuel Morgado Chávez +1

In this project, we employ the short-distance factorization to compute the distribution amplitude of the ${\eta }_c$-meson from Lattice QCD at leading twist. We employ a set of CLS $N_f=…
