Two-particle twist-3 distribution amplitudes of the pion and kaon in the light-front quark model

Ho-Meoyng Choi, Chueng-Ryong Ji

We investigate the two-particle twist-3 distribution amplitudes (DAs) of the pseudoscalar mesons, in particular pseudoscalar (${\varphi }_{3;M}^P(x)$) and pseudotensor (${\varphi }_{3;M}^{\sigma }(x)$) DAs…
