Enriching the Standard ModelImplications for LHC

1. Higgs family has a rich hierarchy While some are heavy to conform to constraints from rare decays, there will be some `pseudo-Goldstone bosons’ that are low.

2. The Higgs bosons are not CP eigenstates and so there will be analogs of KL and KS oscillations.

3. The parameters of CKM matrices related to the hierarchies of Higgs family.
