The discovery of neutrino mass and neutrino oscillation has finally been recognized by the Physics Nobel Prize! The 2015 prize goes to Takaaki Kajita from Super-K and Art McDonald from SNO, recognizing our studies of atmospheric neutrinos and solar neutrinos … Continue reading
Jeff Gustafson’s search for dinucleon decay into pions was published and listed as an Editor’s Suggestion by Physical Review D. His search in three modes was negative but set new lifetime limits more than two orders of magnitude more restrictive … Continue reading
The Super-K collaboration has (finally!) published our paper (M. Litos et al., Phys. Rev. Lett. 112, 131803) based on Mike Litos’ Ph.D. thesis search for dinucleon decay into kaons. This process changes baryon number by two units without any change in … Continue reading
Neil deGrasse Tyson paid a virtual visit to the Super-K detector to discuss supernova neutrinos. The vignette appeared in the April 13 episode of COSMOS, “Deeper, Deeper, Deeper, Still”, Episode 6.
Our paper detailing the asymmetry between the flux of solar neutrinos at night versus daytime: First Indication of Terrestrial Matter Effects on Solar Neutrino Oscillation has been selected as a Physical Review Letters Editors Suggestion as well as Featured in … Continue reading
Our most recent T2K publication (Phys. Rev. Lett. 112, 061802) shows the electron neutrino appearance signal interpreted in comparison with the measurements of electron antineutrino disappearance by the reactor experiments. The paper was featured in a PRL Viewpoint article discussing how … Continue reading
The T2K collaboration is releasing the latest results on electron neutrino appearance, starting with the European Physical Society meeting today. This includes 2013 data taking at 220 kW and a world-record 1.2e14 protons-per-pulse. In the new data we found 28 … Continue reading
The T2K collaboration restarted data taking in early 2012 after recovery efforts from the Great Japan Earthquake of 2011 were completed at J-PARC. We collected an additional 1.6e20 protons on target, somewhat more than doubling the 2011 data set. We … Continue reading
The T2K collaboration has submitted our first physics paper to Physical Review Letters. In it we report the most significant evidence to date that muon neutrinos transform into electron neutrinos. This transformation is governed by a previously unmeasured parameter of … Continue reading
