Abstract
A model relating radiative seesaw and minimal dark matter mass scales without beyond the standard model (SM) gauge symmetry (RνMDM) is constructed. In addition to the SM particles, the RνMDM contains, a Majorana fermion multiplet NR and scalar multiplet χ that transform respectively as (1, 5, 0) and (1, 6,-1/2) under the SM gauge group SU(3)C ×SU(2) L ×U(1)Y . The neutral component N0 R plays the role of dark matter with a mass in the range of 9 to 10TeV. This scale also sets the lower limit for the scale for the heavy degrees of freedom in NR and χ which generate light neutrino masses through the radiative seesaw mechanism. The model predicts an NCR -nucleus scattering cross section that would be accessible with future dark matter direct detection searches as well as observable effects in present and searches for charged lepton flavor violating processes, such as li←l jγ. and μ - e conversion. © SISSA 2011.
