Charmless two-body anti-triplet $b$-baryon decays

Y. K. Hsiao, Yu Yao, C. Q. Geng

We study the charmless two-body decays of $b$-baryons $({\Lambda }_b$, ${\Xi }_b^{-}$, ${\Xi }_b^0)$. We find that $\mathcal{B}({\Xi }_b^{-}\to \Lambda {\rho }^{-})=(2.08_{-0.51}^{+0.69})\times 10^{-6}$ and ${\cal B}(Ξ_b^0\to…
