Higher twist light-cone distribution amplitudes of vector mesons in QCD

Abstract

We present a systematic study of twist-3 light-cone distribution amplitudes of vector mesons in QCD, which is based on conformal expansion. A complete set of distribution amplitudes is constructed for \rho, \omega, K^* and \phi mesons, which satisfies all (exact) equations of motion and constraints from conformal expansion.
