Using $\bar{p}p$ and $e^{+}{e}^{-}$ Annihilation Data to Refine Bounds on the Baryon-Number-Violating Dinucleon Decays $nn\to e^{+}{e}^{-}$ and $nn\to {\mu }^{+}{\mu }^{-}$

Abstract

We use $\bar{p}p$ and $e^{+}{e}^{-}$ annihilation data to further strengthen lower bounds on the partial lifetimes for the baryon-number-violating dinucleon decays $nn\to e^{+}{e}^{-}$ and $nn\to {\mu }^{+}{\mu }^{-}$.
