Do the anomalies observed in the LHCb experiment in the decay of B mesons hide hitherto unknown particles from outside the currently valid and well-tested Standard Model?  "There is strong experimental evidence that there is indeed some new physics lurking in the lepton sector," Dev said.  Now, in a new result unveiled today at the Neutrino 2018 conference in Heidelberg, Germany, the collaboration has announced its first results using antineutrinos, and has seen strong evidence of muon antineutrinos oscillating into electron antineutrinos over long distances, a phenomenon that has never been unambiguously observed.  The Precision Reactor Oscillation and Spectrum Experiment (PROSPECT) has completed the installation of a novel antineutrino detector that will probe the possible existence of a new form of matter.  The MINERvA collaboration analyzed data from the interactions of an antineutrino-the antimatter partner of a neutrino-with a nucleus.  The inclusion of short-range interactions in models of neutrinoless double-beta decay could impact the interpretation of experimental searches for the elusive decay.  The occasional decay of neutrons into dark matter particles could solve a long-standing discrepancy in neutron decay experiments.  The U.S. Department of Energy has approved funding and start of construction for the SuperCDMS SNOLAB experiment, which will begin operations in the early 2020s to hunt for hypothetical dark matter particles called weakly interacting massive particles, or WIMPs.  Thanks to low-noise superconducting quantum amplifiers invented at the University of California, Berkeley, physicists are now embarking on the most sensitive search yet for axions, one of today's top candidates for dark matter.
