Magnetic Moments of Vector Mesons in the Background Field Method

Presenter: Frank X. Lee — George Washington University

Frank X. Lee, Scott Moerschbacher, Walter Wilcox

We report some results for the magnetic moments of vector mesons extracted from mass shifts in the presence of static external magnetic fields. The calculations are done on 244 quenched lattices using standard Wilson actions, with β=6.0 and pion mass down to 500 MeV. The results are compared to those from the form factor method.
