Abstract

We derive the relativistic factor for splitting of the g-factors of a fermion and its antifermion partner, which is important for placing constraints on dimension-five, CPT-odd and Lorentz-invariance-violating interactions from experiments performed in a cyclotron. From existing data, we extract limits (1\ensuremathσ) on the coupling strengths of the temporal component, f⁰, of a background field (including the field amplitude), which is responsible for such g-factor splitting, with an electron, proton, and muon: |f_e⁰|<2.3\ifmmode×\else\texttimes\fi10^\ensuremath-12\ensuremathμ_B, |f_p⁰|<4\ifmmode×\else\texttimes\fi10^\ensuremath-9\ensuremathμ_B, and |f_\ensuremathμ⁰|<8\ifmmode×\else\texttimes\fi10^\ensuremath-11\ensuremathμ_B, respectively, in the laboratory frame (\ensuremathμ_B is the Bohr magneton). From existing data, we also extract limits on the coupling strengths of the spatial components, d^\ensuremath⊥, of related dimension-five interactions of a background field with an electron, proton, neutron, and muon: |d_e^\ensuremath⊥|\ensuremath\lesssim10^\ensuremath-9\ensuremathμ_B, |d_p^\ensuremath⊥|\ensuremath\lesssim10^\ensuremath-9\ensuremathμ_B, |d_n^\ensuremath⊥|\ensuremath\lesssim10^\ensuremath-10\ensuremathμ_B, and |d_\ensuremathμ^\ensuremath⊥|\ensuremath\lesssim10^\ensuremath-9\ensuremathμ_B, respectively, in the laboratory frame.
