On Extra Top Yukawa Couplings of a Second Higgs Doublet
Abstract
:1. Introduction: Historical Development of Extra Top Yukawa Couplings
2. Two Sets of Dimension-4 Dynamical Operators
- CPV for EWBG calls for extra top Yukawa couplings, while first order phase transition calls for Higgs quartics. The latter, in turn, suggests sub-TeV exotic Higgs masses, as we shall see.
- For the electron EDM constraint, the diagonal extra electron Yukawa coupling needs to correlate with extra top Yukawa coupling that echoes the known Yukawa coupling pattern.
3. Driving EWBG and Facing eEDM: Extra tt, tc and ee Couplings
4. Crux of Production at Hadron Colliders: Extra tc Coupling
4.1. Top-Associated Neutral Higgs Production
4.2. Bottom-Associated Charged Higgs Production
4.3. Enter the tu Coupling
5. Turning to Flavor: Ratio of B to Muon+Neutrino vs. Tau+Neutrino
6. Prospects and Conclusions
