Abstract: The leading relativistic and recoil corrections to bound state $g$-factors ofparticles with arbitrary spin are calculated. It is shown that thesecorrections are universal for any spin and depend only on the free particlegyromagnetic ratios. To prove this universality we develop NRQED for chargedparticles with an arbitrary spin. The coefficients in the NRQED Hamiltonian forhigher spin particles are determined only by the requirements of Lorentzinvariance and local charge conservation in the respective relativistic theory.For spin one charged particles the NRQED Hamiltonian follows from therenormalizable QED of the charged vector bosons. We show that universality ofthe leading relativistic and recoil corrections can be explained with the helpof the Bargmann-Michael-Telegdi equation.
