Twist-3 Distribution Amplitudes of Pion in the Light-Front Quark Model
arXiv:1611.03201 · doi:10.1007/s00601-016-1208-8
Abstract
We analyzed two twist-3 distribution amplitudes of pion, i.e. pseudoscalar $Ï^P_{3;Ï}(x)$ and pseudotensor $Ï^Ï_{3;Ï}(x)$, within the LFQM. Our LFQM descriptions both for twist-3 $Ï^P_{3;Ï}$ and $Ï^Ï_{3;Ï}$ not only satisfy the fundamental constraint required from the isospin symmetry, but also reproduce exactly the asymptotic forms anticipated from QCD's conformal limit.
