Experimental Test of Baryon Conservation

Abstract

A 162-${\mathrm{m}}^2$ sr scintillation detector located 3200 m underground was used to look for high-energy fragments from baryon-nonconserving nucleon decay. A new lower limit on the half-life of the nucleon from 2×${10}^{28}$ to 8×${10}^{29}$ years, depending on the assumed decay mode, is established.
