The Polarized Structure Function g_2: A Lattice Study Revisited
/ Authors
/ Abstract
A recent lattice calculation of the spin-dependent structure function g_2 is revisited. It has been recognized that the twist-three operator, which gives rise to d_2, mixes non-perturbatively with operators of lower dimensions under renormalization. This changes the results substantially.
