Model-Independent Results for SU(3) Violation in Twist-3 Light-Cone Distribution Functions

High Energy Physics - Phenomenology 2008-11-26 v3

Abstract

Using chiral symmetry we investigate the leading SU(3) violation in the complete set of quark twist-3 light-cone distribution functions of the pion, kaon, and eta. It is shown that terms non-analytic in the quark masses do not affect the shape, and only appear in the normalization constants. Predictive power is retained including the leading analytic m_{q} operators. With the symmetry violating corrections we derive useful model-independent relations between the distributions of pion, kaon and eta. We also comment on the calculations of the moments of these distributions using lattice QCD and light-cone sum rules.
