Abstract

We analyzed two twist-3 distribution amplitudes of pion, i.e. pseudoscalar ϕ3;πP(x) and pseudotensor ϕ3;πσ(x), within the LFQM. Our LFQM descriptions both for twist-3 ϕ3;πP and ϕ3;πσ obtained from the Gaussian radial wave function not only satisfy the fundamental constraint required from the isospin symmetry, but also reproduce exactly the asymptotic forms anticipated from QCD’s conformal limit.
