Description

Measurements of ${\mathrm{\Lambda }}_b$ decays at the Large Hadron Collider provide complementary constraints on important quantities in flavor physics, and can shed new light on "anomalies" observed in mesonic $b$ decays. In this talk, I will report on lattice QCD calculations of the form factors describing semileptonic and rare ${\mathrm{\Lambda }}_b$ decays, and discuss the phenomenological implications. The topics covered include determinations of $|V_{ub}|$ and $|V_{cb}|$, fits of $|\mathrm{\Delta }B|=|\mathrm{\Delta }S|=1$ Wilson coefficients, and tests of lepton flavor universality.
