Extension of \(\nu\)MSM model and possible explanations of recent astronomical and collider observations
Here I present the extension to \({\nu}\)MSM model by adding a \(U(1)'\) gauge symmetry under which right-handed fermions including sterile neutrinos and exotic Higgs scalar are charged. This model explains 3.5 keV line observed by XMM-Newton telescope as well as Galactic Center Excess(GCE) det...

| description | Here I present the extension to \({\nu}\)MSM model by adding a \(U(1)'\) gauge symmetry under which right-handed fermions including sterile neutrinos and exotic Higgs scalar are charged. This model explains 3.5 keV line observed by XMM-Newton telescope as well as Galactic Center Excess(GCE) detected by Fermi-LAT satellite. The proposed model also accounts for recent diphoton excess of mass around 750 GeV produced in ATLAS and CMS detectors. Cosmological inconsistencies such as baryon asymmetry can also be explained. Verification of presented model is possible with current experimental techniques and limitations. Careful validation and analysis of the model needs to be done in future. |
