Description
I will present a lattice calculation of $\Xi_b \to \Xi$ form factors with application to rare decays, and give an update on my progress toward improved determinations of the $\Lambda_b \to p$, $\Lambda_b \to \Lambda$, and $\Lambda_b \to \Lambda_c$ form factors. An important methodological advance is the use of modified $z$ expansions that include dispersive bounds and asymptotic-behavior constraints to achieve controlled uncertainties in the full kinematic range.
