Two papers by the Super-Kamiokande collaboration documenting analyses by postdoc Alex Himmel and former postdoc Tarek Akiri, both from the neutrino group, were highlighted on the front page of the Physical Review D March 25, 2015.
The first paper "Limits on sterile neutrino mixing using atmospheric neutrinos in Super-Kamiokande" Phys. Rev. D 91, 052019 (2015) sets new limits on hypothetical new non-interacting neutrino types. This was an analysis undertaken by Dr. Himmel.
The second paper "Neutrino Test of Lorentz Invariance" Phys. Rev. D 91, 052003 (2015) was published along with an accompanying viewpoint article. This analysis was based on the work of both Drs. Himmel and Akiri.
