This workshop will explore theoretical and experimental aspects of lepton flavor universality violation and lepton flavor violation in meson and baryon decays. The goal is to discuss questions such as the following:

• What are the future prospects for improved or novel experimental tests of LFU and searches for LFV in hadron decays?
• How far can the uncertainties be reduced, and what input is needed from theory and from other measurements?
• How can we further narrow down the possibilities for new-physics models that may explain the anomalies seen in b -> s l+l- and b -> c l nu decays?
• What correlations are expected between different observables in different models?

This meeting is part of a series of events in the context of Snowmass 2021, and is organized jointly by the topical groups RF1: Weak decays of b and c quarks and RF5: Charged Lepton Flavor Violation (electrons, muons and taus).
