Probing Lepton-Number and Baryon-Number Violating Tau Decays at Belle
Résumé
The standard model of particle physics accidentally conserves lepton number and baryon number. The Belle experiment at the KEKB asymmetric-energy $e^{+}e^{-}$ collider provides an ideal platform to probe lepton number and baryon number violation in the decays of $\tau $ leptons. We report the results on a search for lepton number and baryon number violating decays $\tau ^{-}\rightarrow \overline{p}e^{+}e^{-}$, $pe^{-}e^{-}$, $\overline{p}e^{+}\mu ^{-}$, $\overline{p}e^{-}\mu ^{+}$, $\overline{p}\mu ^{-}\mu ^{+}$, and $p\mu ^{-}\mu ^{-}$ using the data sample collected with the Belle detector.
