CLARK
1981
SPEC ++
1  CLARK 1981 is FNAL experiment with 209 GeV muon. Looked for ${{\mathit \mu}^{+}}$ nucleon $\rightarrow$ ${{\overline{\mathit \mu}}_{{P}}^{0}}$ X, ${{\overline{\mathit \mu}}_{{P}}^{0}}$ $\rightarrow$ ${{\mathit \mu}^{+}}{{\mathit \mu}^{-}}{{\overline{\mathit \nu}}_{{\mu}}}$ and ${{\mathit \mu}^{+}}$ ${{\mathit n}}$ $\rightarrow$ ${{\mathit \mu}_{{P}}^{++}}$ X, ${{\mathit \mu}_{{P}}^{++}}$ $\rightarrow$ 2 ${{\mathit \mu}^{+}}{{\mathit \nu}_{{\mu}}}$ . Above limits are for $\sigma{}{\times }$BR taken from their mass-dependence plot figure 2.
