Magnetic Moment of Vector Mesons in the Background Field Method
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 $24^4$ 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.
