Abstract

I report new, world-leading LHCb results on heavy meson lifetimes. We use a novel approach that suppresses the shortcomings typically associated with reconstruction of semileptonic decays, allowing for precise measurements of lifetimes and other properties in collider experiments. We achieve a 15% and a 2× improvement over current best determinations of the flavor-specific B⁰_s lifetime and D^-_s lifetime, respectively.
