Description
Given the flavour anomalies, one might speculate that baryon number violation involving third family quarks could happen at a much lower scale than the GUT scale. In this talk I will describe how to constrain baryon number violating operators involving a bottom quark from proton lifetime bounds. As a result one can estimate the maximum branching fraction expected in baryon number violating $B$ decays, turning out to be far from current sensitivities at $B$-factories. This in fact discourage direct experimental searches of baryon number violation in $B$ decays.
