Neutrino Portal via Loops
Wei Chao
One loop correction to the dark matter (DM) annihilation cross section is usually assumed to be sub-dominate in calculating the DM relic density. In this paper, we propose a scenar…
Hybrid Dark Matter
Wei Chao
Dark matter can be produced in the early universe via the freeze-in or freeze-out mechanisms. Both scenarios were investigated in references, but the production of dark matters via…
Phenomenology of the gauge symmetry for right-handed fermions
Wei Chao
In this paper we investigate the phenomenology of the U(1) gauge symmetry for right-handed fermions, where three right-handed neutrinos are introduced for anomalies cancellation. C…
Hiding Scalar Higgs Portal Dark Matter
Wei Chao
We investigate a Higgs portal dark matter model by extending the Standard model (SM) with a complex singlet, , where is a dark matter candidate and get…
The Diphoton Excess Inspired Electroweak Baryogenesis
Wei Chao
A resonance in the diphoton channel with invariant mass GeV was claimed by the ATLAS and CMS collaborations at the run-2 LHC with TeV. In this paper, w…
The Diphoton Excess from an Exceptional Supersymmetric Standard Model
Wei Chao
In this paper we explain the diphoton excess in the invariant mass M 750 GeV , claimed by the ATLAS and CMS collaborations at the run-2 LHC, as the signal of a scalar sin…
Neutrino Catalyzed Diphoton Excess
Wei Chao
In this paper we explain the 750 GeV diphoton resonance observed at the run-2 LHC as a scalar singlet , that plays a key rule in generating tiny but nonzero Majorana neutrino ma…
Symmetries Behind the 750 GeV Diphoton Excess
Wei Chao
A 750 GeV resonance has been observed at the Run 2 LHC in the diphoton channel. In this paper, we explain this resonance as a CP-even scalar, S, that triggers the spontaneous break…
ATLAS Diboson Excesses from the Stealth Doublet Model
Wei Chao
The ATLAS collaboration has reported excesses in diboson invariant mass searches of new resonances around 2 TeV, which might be a prediction of new physics around that mass range.…
First order electroweak phase transition triggered by the Higgs portal vector dark matter
Wei Chao
We investigate an extension of the Standard Model (SM) with a U(1)' gauge symmetry, which is spontaneously broken by a complex scalar singlet and where the new gauge boson is a sta…
Electroweak Baryogenesis in the Exceptional Supersymmetric Standard Model
Wei Chao
We study electroweak baryogenesis in the E_6 inspired exceptional supersymmetric standard model ( E_6SSM ). The relaxation coefficients driven by singlinos and the new gaugino as w…
The Higgs Seesaw Induced Neutrino Masses and Dark Matter
Yi Cai, Wei Chao
In this paper we propose a possible explanation of the active neutrino Majorana masses with the TeV scale new physics which also provide a dark matter candidate. We extend the Stan…
Electroweak Baryogenesis, Electric Dipole Moments, and Higgs Diphoton Decays
Wei Chao, Michael J. Ramsey-Musolf
We study the viability of electroweak baryogenesis in a two Higgs doublet model scenario augmented by vector-like, electroweakly interacting fermions. Considering a limited, but il…
Hidden from View: Neutrino Masses, Dark Matter and TeV-Scale Leptogenesis in a Neutrinophilic 2HDM
Wei Chao, Michael J. Ramsey-Musolf
We consider a simple extension of the Standard Model providing dark matter and a TeV-scale seesaw mechanism that also allows for viable leptogenesis. In addition to the Standard Mo…
Higgs Vacuum Stability, Neutrino Mass, and Dark Matter
Wei Chao, Matthew Gonderinger, Michael J. Ramsey-Musolf
Recent results from ATLAS and CMS point to a narrow range for the Higgs mass: . Given this range, a case may be made for new physics beyond the Standar…
Dark Matter, LFV and Neutrino Magnetic Moment in the Radiative Seesaw Model with Triplet Fermion
Wei Chao
In this paper we work in the framework of a radiative seesaw model with triplet fermion . Due to the discrete flavor symmetry, the lightest neutral component of is sta…
A Three Higgs Doublet Model for the Fermion Mass Hierarchy Problem
Wei Chao
In this paper we propose a possible explanation to the Fermion mass hierarchy problem by fitting the type-II seesaw mechanism into the Higgs doublet sector, such that their vacuum…
Neutrino Masses, Dark Matter and B-L Symmetry at the LHC
Tong Li, Wei Chao
We establish a hybrid seesaw mechanism to explain small neutrino masses and predict cold dark matter candidate in the context of the B-L gauge symmetry extension of the Standard Mo…
Neutrino Masses and A TeV Scale Seesaw Mechanism
Wei Chao
A simple extension of the Standard Model providing TeV scale seesaw mechanism is presented. Beside the Standard Model particles and right-handed Majorana neutrinos, the model conta…
Neutrino Masses and Lepton-flavor-violating Decays in the Supersymmetric Left-right Model
Wei Chao
In the supersymmetric left-right model, the light neutrino masses are given by the Type-II seesaw mechanism. A duality property about this mechanism indicates that there exist eigh…
