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

TL;DR

This paper refines lower bounds on the lifetimes of baryon-number-violating dinucleon decays into electron and muon pairs by analyzing existing $ar p p$ and $e^+e^-$ annihilation data.

Contribution

It introduces new constraints on dinucleon decay processes by utilizing existing particle collision data, improving previous bounds on baryon-number violation.

Findings

Stronger lower bounds on $nn o e^+ e^-$ decay lifetime.

Enhanced limits on $nn o \mu^+\mu^-$ decay lifetime.

Utilization of $ar p p$ and $e^+e^-$ data to constrain baryon-number violation.

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 $nn \to \mu^+\mu^-$.
