Decadal Mission for the New Physics Higgs/Flavor Era
Abstract
The LHC has not discovered any New Physics beyond the anticipated boson, and new ideas abound for out-of-the-box searches, or Effective Field Theories with multi-TeV cutoff. But, have we exhausted dimension-4 operators involving sub-TeV particles that are {\it not} exotic (non-XLP)? We advocate the existence of an extra Higgs doublet that carry extra Weinberg couplings, where {\it emergent} mass-mixing hierarchies {\it and} alignment have hidden their effects very well so far. Higgs quartics can induce first order electroweak phase transition and imply sub-TeV spectrum. The extra Weinberg couplings, led by and at , can drive electroweak baryogenesis, while , the ratio of usual electron and top Weinberg couplings, can tame electron EDM. Finding these extra Higgs bosons via , and processes (and those allowed by Higgs boson splittings) at the LHC, and pushing the flavor frontier to break the flavor code, would usher in a new Higgs/flavor era. A new scale at 10--20 TeV, possibly related to the Landau pole of the scalar sector, may emerge.
