What is the gyromagnetic ratio of spin-1 mesons?

[davidmaalve]

Hello all. Would anybody know where I can find data on gyromagnetic ratios/magnetic moments/g-factors of mesons? I find everything about nucleons, electrons and muons, but that's about where it stops. Even the Particle Data Groups is silent about it. Or is there any reason why it is not possible to measure/define this?

The lifetimes of vector mesons (which might have mag moms) are too short to measure a mag mom. The quark model does give simple predictions for their mag moms and g factors,

Spin-0 mesons have no magnetic moments. As Meir Achuz points out, spin-1 mesons do, but the only way one can measure this is indirectly.
