Recently Coleman and Glashow [Phys. Lett. B 405 (1997) 249; Harvard University Theoretical Physics Preprint 98/AO76 (pvt. comm)] have developed a model which allows the introduction of a small violation of Lorentz invariance. Observational signatures arise because this interaction also violates flavor conservation and allows the radiative decay of the muon, μ→e+γ, whose branching ratio increases as bγ4 where γ is the Lorentz factor of the muon with respect to the reference frame in which the dipole anisotropy of the universal microwave radiation vanishes. In this paper we place a bound on the Lorentz invariance violating parameter, b, of b<10−25 based on observations of horizontal air showers with ne≥5×106. With such small values of b the proposed radiative decay of the muon will not affect the functioning of the muon collider. |
