Title: Neutrino Masses and Sterile Neutrino Dark Matter from the PeV Scale
Host: Yuhsin
Room: 432
Abstract: The Higgs boson mass of 125 GeV is suggestive of superpartners at the PeV scale. This talk discusses how new physics at this scale can also produce active neutrino masses via a modified, low energy seesaw mechanism and provide a sterile neutrino dark matter candidate with keV-GeV scale mass. These emerge in a straightforward manner if the right-handed neutrinos are charged under a new symmetry broken by a scalar field vacuum expectation value at the PeV scale. Possible connections to the 3.5 keV X-ray line and the PeV neutrino events at IceCube will also be discussed.
