Abstract
A new upper limit for the probability of spontaneous muonium to antimuonium conversion was established at ( C.L.) in 0.1 T magnetic field, which implies consequences for speculative extensions to the standard model. Coupling parameters in -parity-violating supersymmetry and the mass of a flavor diagonal bileptonic gauge boson can be significantly restricted. A model with radiative mass generation through heavy lepton seed and the minimal version of 331 models are disfavored.
