Light Resonances and the Low- Bin of
Wolfgang Altmannshofer, Michael J. Baker, Stefania Gori +4
LHCb has reported hints of lepton-flavor universality violation in the rare decays , both in high- and low- bins. Although the high- hint may…
Signatures of Dark Radiation in Neutrino and Dark Matter Detectors
Yanou Cui, Maxim Pospelov, Josef Pradler
We consider the generic possibility that the Universe's energy budget includes some form of relativistic or semi-relativistic dark radiation (DR) with non-gravitational interaction…
Directly Detecting MeV-scale Dark Matter via Solar Reflection
Haipeng An, Maxim Pospelov, Josef Pradler +1
If dark matter (DM) particles are lighter than a few MeV/ and can scatter off electrons, their interaction within the solar interior results in a considerable hardening of the…
US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
Dark forces coupled to non-conserved currents
Jeff A. Dror, Robert Lasenby, Maxim Pospelov
New light vectors with dimension-4 couplings to Standard Model states have (energy / vector mass)^2 enhanced production rates unless the current they couple to is conserved. These…
BBN for the LHC: constraints on lifetimes of the Higgs portal scalars
Anthony Fradette, Maxim Pospelov
LHC experiments can provide a remarkable sensitivity to exotic metastable massive particles, decaying with significant displacement from the interaction point. The best sensitivity…
