More on R-parity and lepton-family number violating couplings from muon(ium) conversion, and τand ${\pi }^0$ decays

Jihn E. Kim, Pyungwon Ko, Dae-Gyu Lee

We present a new class of constraints to the lepton-family number and R-parity violating couplings from muonium conversion, ${\mu }^{-}+{}_{22}^{48}Ti\to e^{-}+{}_{22}^{48}Ti$, a…
