Probing the two-neutrino exchange force using atomic parity violation
Mitrajyoti Ghosh, Yuval Grossman, Walter Tangarife
The exchange of two neutrinos at one loop leads to a long-range parity-violating force between fermions. We explore the two-neutrino force in the backdrop of atomic physics. We poi…
Dodelson-Widrow Mechanism In the Presence of Self-Interacting Neutrinos
André de Gouvêa, Manibrata Sen, Walter Tangarife +1
keV-scale gauge-singlet fermions, allowed to mix with the active neutrinos, are elegant dark matter (DM) candidates. They are produced in the early universe via the Dodelson-Widrow…
Singlet-Doublet Dirac Dark Matter and Neutrino Masses
Diego Restrepo, Andrés Rivera, Walter Tangarife
We examine an extension of the Standard Model that addresses the dark matter puzzle and generates Dirac neutrinos masses through the radiative seesaw mechanism. The new field conte…
