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…
New constraints on light vectors coupled to anomalous currents
Jeff A. Dror, Robert Lasenby, Maxim Pospelov
We derive new constraints on light vectors coupled to Standard Model (SM) fermions, when the corresponding SM current is broken by the chiral anomaly. Cancellation of the anomaly b…
Black Hole Superradiance Signatures of Ultralight Vectors
Masha Baryakhtar, Robert Lasenby, Mae Teo
The process of superradiance can extract angular momentum and energy from astrophysical black holes (BHs) to populate gravitationally-bound states with an exponentially large numbe…
