Description
In this talk, I review recent progress in the theoretical description of heavy-hadron lifetimes across different flavor systems, ranging from heavy–light mesons and baryons to doubly heavy hadrons and the Bc meson. I discuss how different mechanisms contribute to lifetime differences among hadrons with the same heavy quark, and how these effects can be quantified using nonperturbative inputs such as NRQCD and lattice QCD.
I will compare theoretical predictions with available experimental measurements and highlight the remaining theoretical uncertainties.
These studies provide a coherent picture of heavy-hadron lifetimes across flavor systems and offer important benchmarks for testing our understanding of heavy quark weak decays and nonperturbative QCD.
