Magnetic moments of vector, axial, and tensor mesons in lattice QCD

Understand

We present a calculation of magnetic moments for selected spin-1 mesons using the techniques of lattice QCD.

• This is carried out by introducing progressively small static magnetic field on the lattice and measuring the linear response of a hadron's mass shift.
• The calculations are done on $24^4$ quenched lattices using standard Wilson actions, with $\beta$=6.0 and pion mass down to 500 MeV.
• The results are compared to those from the form factor method where available.
