Twin Higgs With T parity
Jiang-Hao Yu
In twin Higgs models, a discrete Z2 symmetry between the standard model Higgs and the twin Higgs is introduced to address the hierarchy problem. In this work, we propose another di…
A Tale of Two Twin Higgses: Addressing Little Hierarchy in Natural 2HDM Framework
Jiang-Hao Yu
In original twin Higgs model, vacuum misalignment between electroweak and new physics scales is realized by adding explicit breaking term. Introducing additional twi…
The Radiative Z2 Breaking Twin Higgs
Jiang-Hao Yu
In twin Higgs model, the Higgs boson mass is protected by a symmetry. The symmetry needs to be broken either explicitly or spontaneously to obtain misalignment between…
SU(2) x SU(2) x U(1) Interpretation on the 750 GeV Diphoton Excess
Jing Ren, Jiang-Hao Yu
We propose that the SU(2) x SU(2) x U(1) (aka G221) models could provide us a 750 GeV scalar resonance that may account for the diphoton excess observed at the LHC while satisfying…
Indirect Detection Imprint of a CP Violating Dark Sector
Wei Chao, Michael J. Ramsey-Musolf, Jiang-Hao Yu
We introduce a simple scenario involving fermionic dark matter () and singlet scalar mediators that may account for the Galactic Center GeV -ray excess while satisfying prese…
Hidden Gauged U(1) Model: Unifying Scotogenic Neutrino and Flavor Dark Matter
Jiang-Hao Yu
In both scotogenic neutrino and flavor dark matter models, the dark sector communicates with the standard model fermions via Yukawa portal couplings. We propose an economic scenari…
The Minimal Scalar-Stealth Top Interpretation of the Diphoton Excess
Wei Chao, Ran Huo, Jiang-Hao Yu
A resonance near 750 GeV has been observed at both the ATLAS and CMS experiments in its diphoton decay channel. We propose a possible interpretation based on a simplified model: a…
