There has been considerable interest in non-standard interactions (NSI) between neutrinos, and these can assist in production of sterile neutrino dark matter. In a paper with Cannon Vogel and Helena García Escudero, we find that vector-mediated NSI are excluded as a mechanism for sterile neutrino dark matter production, due to a combination of laboratory and structure formation constraints. Scalar mediated NSI and low reheating temperature models remain viable.

"After measuring the wobbles of 300 billion muons, the Muon g − 2 Collaboration has pinpointed with exquisite precision the internal magnetism of these subatomic particles. [...] In a somewhat surprising turn of events, the final results from the Muon g − 2 experiment line up with the most recent predictions, further validating the standard model of particle physics."

Physics · Muon Experiment Calls It a WrapThe final results from the Muon g − 2 experiment agree with the latest predictions of the muon’s magnetic properties—letting down hopes that the particle would upset the standard model’s applecart.

ScienceDailyStrange “heavy” electrons could be the future of quantum computingScientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a deep quantum link, and doing so in ways tied to the fastest possible time in physics. Even more surprising, the effect appeared close to room temperature, hinting that future quantum computers might harness this bizarre state of matter.
