Origin of Sterile Neutrino Dark Matter via Vector Secret Neutrino Interactions
Kevin J. Kelly, Manibrata Sen, Walter Tangarife +1
Secret neutrino interactions can play an essential role in the origin of dark matter. We present an anatomy of production mechanisms for sterile neutrino dark matter, a keV-scale g…
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…
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…
Accretion of Dissipative Dark Matter onto Active Galactic Nuclei
Nadav Joseph Outmezguine, Oren Slone, Walter Tangarife +2
We examine the possibility that accretion of Dissipative Dark Matter (DDM) onto Active Galactic Nuclei (AGN) contributes to the growth rate of Super Massive Black Holes (SMBHs). Su…
Relaxed Inflation
Walter Tangarife, Kohsaku Tobioka, Lorenzo Ubaldi +1
We present an effective model where the inflaton is a relaxion that scans the Higgs mass and sets it at the weak scale. The dynamics consist of a long epoch in which inflation is d…
Radiative neutrino masses in the singlet-doublet fermion dark matter model with scalar singlets
Diego Restrepo, Andrés Rivera, Marta Sánchez-Peláez +2
When the singlet-doublet fermion dark matter model is extended with additional --odd real singlet scalars, neutrino masses and mixings can be generated at one-loop level. In t…
