The Next-to-Minimal Two Higgs Doublet Model
Chien-Yi Chen, Michael Freid, Marc Sher
The simplest extension of the Two Higgs Doublet Model is the addition of a real scalar singlet, S. The effects of mixing between the singlet and the doublets can be manifested in t…
Electroweak Effective Operators and Higgs Physics
Chien-Yi Chen, S. Dawson, Cen Zhang
We derive bounds from oblique parameters on the dimension-6 operators of an effective field theory of electroweak gauge bosons and the Higgs doublet. The loop- induced contribution…
Standard Model Explanation of the Ultra-high Energy Neutrino Events at IceCube
Chien-Yi Chen, P. S. Bhupal Dev, Amarjit Soni
The recent observation of two PeV events at IceCube, followed by an additional 26 events between 30 - 300 TeV, has generated considerable speculations on its origin, and many exoti…
Projections for Two Higgs Doublet Models at the LHC and ILC: A Snowmass White Paper
Chien-Yi Chen
The discovery of the 125 GeV Higgs boson and the measurement of its branching ratios has initiated the exploration of the electroweak symmetry breaking sector. There have been nume…
Probing Heavy-Light Neutrino Mixing in Left-Right Seesaw Models at the LHC
Chien-Yi Chen, P. S. Bhupal Dev, R. N. Mohapatra
We show that in TeV-scale left-right (L-R) symmetric seesaw models, there are new dominant contributions to the collider signals of heavy Majorana neutrinos arising from the heavy-…
Heavy Higgs Searches and Constraints on Two Higgs Doublet Models
Chien-Yi Chen, S. Dawson, Marc Sher
Since the discovery of a Higgs boson at the LHC and the measurement of many of its branching ratios, there have been numerous studies exploring the restrictions these results place…
