Breakthrough Prize for Super-K and T2K

Super-K, K2K and T2K (the latter two combined) were recognized along with Daya Bay, KamLAND and SNO by the Breakthrough Prize Foundation, a relatively new award.  The awarded for Super-K  was received by Kajita and Suzuki, with authors of the 1998 and 2001 atmospheric neutrino and solar neutrino papers being named as co-laureates. The K2K/T2K award was received by Nishikawa and likewise, numerous authors of key papers were named as co-laureates.

Kajita and McDonald win Nobel for neutrino oscillations

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 as the key to recognizing that neutrinos change from one flavor into another and that neutrinos have mass.

Dinucleon decay into pions published and highlighted.

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 than those of previous searches. http://journals.aps.org/prd/abstract/10.1103/PhysRevD.91.072009

Dinucleon decay paper published in PRL

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 lepton number, and therefore is sensitive to very different underlying physics than most nucleon decay searches. This particular mode is allowed in supersymmetric models that have R-symmetry violation. A possible Feynman diagram is shown below. This is the first ever search for a baryon number violating process that also changes strangeness by two units.

Super-Kamioka appears in COSMOS

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 Physics. It is also being reviewed by articles in Physics Today, Physics World (UK) and Physics Focus by the APS.

T2K Result Featured by PRL

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 these results are first steps along the path towards observing CP violation in neutrinos.
