Flavor SU(3) and $\Lambda_b$ decays

Some flavor SU(3) results are presented for decays of the $\Lambda_b$ baryon into non-charmed final states $PB$, where $P$ is a pseudoscalar mesons and $B$ is a spin-1/2 baryon. Although these relations are among amplitudes and hence not yet subject to direct experimental test, they can form the basis for triangle inequalities among decay rates.
