A 40%‐asymmetry has been revealed in the hard scattering region at 40 GeV. Systematic errors in the experiment are noticeable. The observed effect requires detailed discussion of the production mechanisms.

In the standard model lepton number violating processes are forbidden, but are allowed in many extensions to it. Muonium to antimuonium conversion has been explicitly allowed in the framework of left‐right‐symmetric models or in supersymmetric mo
