Flavor and CP invariant composite Higgs models

The avor protection in composite Higgs models with partial compositeness is known to be insuffcient. We explore the possibility to alleviate the tension with CP odd observables by assuming that avor or CP are symmetries of the composite sector, broken by the coupling to Standard Model fields. One realization is that the composite sector has a avor symmetry SU(3) or SU(3) _U ⊗ SU(3)_D which allows us to realize Minimal Flavor Violation. We show how to avoid the previously problematic tension between a avor symmetric composite sector and electro-weak precision tests. Some of the light quarks are substantially or even fully composite with striking signals at the LHC. We discuss the constraints from recent dijet mass measurements and give an outlook on the discovery potential. We also present a different protection mechanism where we separate the generation of avor hierarchies and the origin of CP violation. This can eliminate or safely reduce unwanted CP violating effects, realizing effectively \Minimal CP Violation" and is compatible with a dynamical generation of avor at low scales.
