The Bearable Compositeness of Leptons

Understand

Partial compositeness as a theory of flavor in the lepton sector is assessed.

• We begin presenting the first systematic analysis of neutrino mass generation in this context, and identifying the distinctive mass textures.
• We then update the bounds from charged lepton flavor and CP violating observables.
• We put forward a $U(1)^3\times CP$ symmetry of the composite sector, in order to allow the new physics to be not far above the TeV scale.
