Abstract
Using lattice QCD, we calculate the twist-2 contribution a(2) to the third Mellin moment of the spin structure functions g(1) and g(2) in the nucleon. In addition we evaluate the twist-3 contribution d(2). Our computations make use of N-f = 2 + 1 gauge field ensembles generated by the Coordinated Lattice Simulations effort. Neglecting quark-line disconnected contributions we obtain as our best ...
