Magnetic Moments of Negative-Parity Baryons from Lattice QCD
Abstract
We report preliminary results for the magnetic moments of negative-parity baryons extracted from mass shifts in the presence of static external magnetic fields. The calculations are done on 243× 48 quenched lattices using standard Wilson actions, with β=6.0 and pion mass down to about 520 MeV, and 1000 configurations. Reasonable signals for the negative-parity states are observed and the sign of their magnetic moments is established. The results are compared to model calculations.
