Abstract

A model relating radiative seesaw and minimal dark matter mass scales without beyond the standard model (SM) gauge symmetry (Rν\nuMDM) is constructed. In addition to the SM particles, the Rν\nuMDM contains, a Majorana fermion multiplet NRN_R and scalar multiplet χ\chi that transform respectively as (1,5,0)(1,5,0) and (1,6,1/2)(1,6,-1/2) under the SM gauge group SU(3)C×SU(2)L×U(1)YSU(3)_C\times SU(2)_L\times U(1)_Y. The neutral component NR0N_R^0 plays the role of dark matter with a mass in the range of 9 to 10 TeV. This scale also sets the lower limit for the scale for the heavy degrees of freedom in NRN_R and χ\chi which generate light neutrino masses through the radiative seesaw mechanism. The model predicts an NR0N_R^0-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 liljγl_i\to l_j \gamma and μe\mu - e conversion.
