Twist-3 Distribution Amplitudes of Pion in the Light-Front Quark Model

Abstract

We analyzed two twist-3 distribution amplitudes of pion, i.e. pseudoscalar ${\varphi }_{3;\pi }^P(x)$ and pseudotensor ${\varphi }_{3;\pi }^{\sigma }(x)$, within the LFQM. Our LFQM descriptions both for twist-3 ${\varphi }_{3;\pi }^P$ and ${\varphi }_{3;\pi }^{\sigma }$ not only satisfy the fundamental constraint required from the isospin symmetry, but also reproduce exactly the asymptotic forms anticipated from QCD's conformal limit.
