Abstract
A new upper limit for the probability of spontaneous muonium to antimuonium conversion was established at (90%C.L.) in 0.1~T magnetic field, which implies consequences for speculative extensions to the standard model. Coupling parameters in R-parity violating supersymmetry and the mass of a flavour diagonal bileptonic gauge boson can be significantly restricted. A Z model with radiative mass generation through heavy lepton seed and the minimal version of 331-GUT models are ruled out.
