Minimal dark origin of a massless Dirac neutrino
P. S. Bhupal Dev, Julia Gehrlein, Amartya Sengupta +1
We propose a gauge-symmetry origin of a rank-two Dirac neutrino mass matrix that enforces one exactly massless neutrino, while being consistent with the oscillation data, as well a…
Ruling Out Spiky WIMP Dark Matter using Indirect Searches
Dibya S. Chattopadhyay, P. S. Bhupal Dev, Yago Porto
The dark matter (DM) density profile in the innermost region of the Galaxy remains an open question. In particular, while adiabatic growth of the supermassive black hole Sgr A$^\as…
Neutrino Non-Standard Interactions from LLE-type R-parity Violation
Fang Xu
We study neutrino non-standard interactions (NSI) induced by the trilinear couplings in -parity-violating supersymmetry in a split-family spectrum where third-generation s…
Relic neutrino decay solution to the excess radio background
P. S. Bhupal Dev, Pasquale Di Bari, Ivan Martínez-Soler +1
The excess radio background detected by ARCADE 2 represents a puzzle within the standard cosmological model. There is no clear viable astrophysical solution, and therefore, it migh…
On the Galactic radio signal from stimulated decay of axion dark matter
P. S. Bhupal Dev, Francesc Ferrer, Takuya Okawa
We study the full-sky distribution of the radio emission from the stimulated decay of axions which are assumed to compose the dark matter in the Galaxy. Besides the constant extrag…
Light scalars in neutron star mergers
P. S. Bhupal Dev, Jean-François Fortin, Steven P. Harris +2
Due to their unique set of multimessenger signals, neutron star mergers have emerged as a novel environment for studies of new physics beyond the Standard Model (SM). As a case stu…
