Abstract
A new result from searching for muonium to antimuonium conversion is reported which sets an upper limit on the coupling constant in an assumed (V-A) × (V-A) type interaction of GMM ≤ 3· 10-3 GF ~ (90% C.L.). A particular Z8 and a minimal 331 GUT model can be ruled out. Further new and stringent limits can be set for masses of bileptonic gauge bosons and λ parameters in R-parity breaking supersymmetric models.
