The Polarized Structure Function g_2: A Lattice Study Revisited
M. Göckeler, R. Horsley, W. Kürzinger +3
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-per…
Baryon Distribution Amplitudes in QCD
V. M. Braun, S. E. Derkachov, G. P. Korchemsky +1
We develop a new theoretical framework for the description of leading twist light-cone baryon distribution amplitudes which is based on integrability of the helicity evolut…
Random Matrix Theory and Chiral Logarithms
M. E. Berbenni-Bitsch, M. Göckeler, H. Hehl +4
Recently, the contributions of chiral logarithms predicted by quenched chiral perturbation theory have been extracted from lattice calculations of hadron masses. We argue that a de…
