Implications of a Light "Dark Higgs" Solution to the Discrepancy
Chien-Yi Chen, Hooman Davoudiasl, William J. Marciano +1
A light scalar with mass GeV and muonic coupling would explain the 3.5 discrepancy between the Standard Model (SM) muon prediction…
Probing triple-Higgs productions via decay channel at a 100 TeV hadron collider
Chien-Yi Chen, Qi-Shu Yan, Xiaoran Zhao +2
The quartic self-coupling of the Standard Model Higgs boson can only be measured by observing the triple-Higgs production process, but it is challenging for the Large Hadron Collid…
Higgs CP Violation from Vectorlike Quarks
Chien-Yi Chen, S. Dawson, Yue Zhang
We explore CP violating aspects in the Higgs sector of models where new vectorlike quarks carry Yukawa couplings mainly to the third generation quarks of the Standard Model. We poi…
Complementarity of LHC and EDMs for Exploring Higgs CP Violation
Chien-Yi Chen, S. Dawson, Yue Zhang
We analyze the constraints on a CP-violating, flavor conserving, two Higgs doublet model from the measurements of Higgs properties and from the search for heavy Higgs bosons at LHC…
Photon Cascade Decay of the Warped Graviton at LHC14 and a 100 TeV Hadron Collider
Kaustubh Agashe, Chien-Yi Chen, Hooman Davoudiasl +1
In warped 5D models of hierarchy and flavor, the first Kaluza-Klein (KK) state of the graviton is heavy enough to decay into a photon and its first KK mode on-shell: $G…
