Abstract We explain the 750  GeV diphoton resonance in the context of the dark left–right symmetric model. A global symmetry in this model, stabilizes the dark matter and ensures that the scalar couples dominantly to gluons and photons. The branching fraction of the scalar to diphoton is large as a consequence of the symmetries of the theory. The benchmark values assumed to fit the diphoton signal also give the correct relic density of dark matter and muon ( g − 2 ) . A specific prediction of… Expand

Asymmetric dark matter models and the LHC diphoton excess
The existence of dark matter (DM) and the origin of the baryon asymmetry are persistent indications that the SM is incomplete. More recently, the ATLAS and CMS experiments have observed an excess ofExpand
Diphoton Excess and Running Couplings
The recently observed diphoton excess at the LHC may suggest the existence of a singlet (pseudo-)scalar particle with a mass of 750 GeV which couples to gluons and photons. Assuming that theExpand
750 GeV diphoton excess at CERN LHC from a dark sector assisted scalar decay
We present a simple extension of the Standard Model (SM) to explain the recent diphoton excess, reported by CMS and ATLAS at CERN LHC. The SM is extended by a dark sector including a vector-likeExpand
Minimal dilaton model and the diphoton excess
In light of the recent 750 GeV diphoton excesses reported by the ATLAS and CMS collaborations, we investigate the possibility of explaining this excess using the minimal dilaton model. We find thatExpand
750 GeV diphoton resonance as a singlet scalar in an extra dimensional model
We interpret the 750 GeV diphoton excess recently found in the 13 TeV LHC data as a singlet scalar in an extra dimensional model, where one extra dimension is introduced. In the model, the scalarExpand
Perturbativity, vacuum stability and inflation in the light of 750 GeV diphoton excess
The recent observation of the 750 GeV diphoton excess at 13 TeV LHC has motivated many scenarios of physics beyond the Standard Model. In this work, we begin by showing that many models which explainExpand
Indirect signature of dark matter with the diphoton resonance at 750 GeV
Motivated by the recently reported diphoton resonance at 750 GeV, we study a new axion-like bosonic portal model of dark matter physics. When the resonance particle is identified as the pseudo-scalarExpand

We investigate a possibility for explaining the recently announced 750 GeV diphoton excess by the ATLAS and the CMS experiments at the CERN LHC in a model with multiple doubly charged particles,Expand
Interpreting the 750 GeV diphoton excess in minimal extensions of Two-Higgs-Doublet models
Abstract It is shown that the 750 GeV diphoton excess can be explained in extensions of Two-Higgs-Doublet Models that do not involve large multiplicities of new electromagnetically charged states.Expand
Physics implications of the diphoton excess from the perspective of renormalization group flow
A very plausible explanation for the recently observed diphoton excess at the 13 TeV LHC is a (pseudo)scalar with mass around 750 GeV, which couples to a gluon pair and to a photon pair through loopsExpand
