Neutrino-Antineutrino Conversion from Ultralight Vector Dark Matter
Asher Berlin, Rodolfo Capdevilla, Ting Cheng +2
We show that Majorana neutrinos convert into antineutrinos in a background of ultralight vector dark matter coupled to lepton number, such as the gauge boson of …
Narrowing Down Sources of High-Frequency Gravitational Waves
Asher Berlin, Dawid Brzeminski, Erwin H. Tanin
Detecting gravitational waves above 100 kHz would constitute a major discovery, as any observable signal would have to arise from new physics within the late universe. Although man…
Electric Accumulation of Millicharged Particles
Asher Berlin, Zachary Bogorad, Peter W. Graham +1
A terrestrial population of millicharged particles that interact significantly with normal matter can arise if they make up a dark matter subcomponent or if they are light enough t…
Cavendish Tests of Millicharged Particles
Asher Berlin, Zachary Bogorad, Peter W. Graham +1
A terrestrial population of room-temperature millicharged particles can arise if they make up a dark matter subcomponent or if they are light enough to be produced in cosmic ray ai…
dSphobic Dark Matter
Asher Berlin, Joshua W. Foster, Dan Hooper +1
We present a mechanism that allows thermal relic dark matter to annihilate efficiently in the Galactic Halo and in galaxy clusters, but not in the lower-velocity environments of dw…
Direct Deflection of Millicharged Radiation
Asher Berlin, Surjeet Rajendran, Harikrishnan Ramani +1
Millicharged particles are generic in theories of dark sectors. A cosmic or local abundance of them may be produced by the early universe, stellar environments, or the decay or ann…
