Earth-bound Milli-charge Relics
Maxim Pospelov, Harikrishnan Ramani
Dark sector particles with small electric charge, or millicharge, (mCPs) may lead to a variety of diverse phenomena in particle physics, astrophysics and cosmology. Assuming their…
Millicharged Cosmic Rays and Low Recoil Detectors
Roni Harnik, Ryan Plestid, Maxim Pospelov +1
We consider the production of a "fast flux" of hypothetical millicharged particles (mCPs) in the interstellar medium (ISM). We consider two possible sources induced by cosmic rays:…
A Composite Solution to the Neutron Bottle Anomaly
Surjeet Rajendran, Harikrishnan Ramani
Measurements of the lifetime of neutrons trapped in a bottle have been consistently shorter than the lifetime measured in neutron beam experiments. With trapping potentials as low…
Muon g-2 and EDM experiments as muonic dark matter detectors
Ryan Janish, Harikrishnan Ramani
The detection of ultralight dark matter through interactions with nucleons, electrons, and photons has been explored in depth. In this work we propose to use precision muon experim…
Observability of Dark Matter Substructure with Pulsar Timing Correlations
Harikrishnan Ramani, Tanner Trickle, Kathryn M. Zurek
Dark matter substructure on small scales is currently weakly constrained, and its study may shed light on the nature of the dark matter. In this work we study the gravitational eff…
