Description
Searches for processes in which baryon number is violated by 2, as would be observed in neutron-antineutron oscillation, have so far come up empty. Many of these searches involve first-generation quarks leaving open the possibility that these processes preferentially couple to initial or final states involving second- and third-generation quarks. We present the results of a search for $B^+\to p\, \Lambda$ decays, which violates baryon-number by 2. The analysis uses the full data set of about 430 $\text{fb}^{-1}$ collected at the $\Upsilon(4{\mathrm{S}})$ resonance by the $BABAR$ experiment, at the $e^+e^-$ collider PEP-II
