The Stony Brook Nucleon decay and Neutrino (NN) Group's main research areas cover forefront of Particle-Astrophysics:
  • T2K (current)
  • Super-Kamiokande (current)
  • DUNE (current)
    • ProtoDUNE SP
    • DUNE 3DSTS (past)
    • Field Cage of Near and Far Detector
  • CAPTAIN (current)
  • K2K (past)
  • HUSEP (past)
  • UNO (past)

The group's research goal is to further pursue discoveries of new and rare phenomena (such as proton decay, neutrinos from supernovae, etc.), and to make precision measurements of lepton mixing matrix elements including the CP violating phase. In order to achieve this goal we are currently involved in two on-going experiments (SuperK and T2K). In the past, we were involved in the K2K experiment that was completed in 2007. We also led, with Jung as the Spokesperson, the HUSEP (Henderson Underground Science and Engineering Project) collaboration to develop a large underground research facility in the Henderson mine at Empire, Colorado.

The Henderson mine was one of the two final candidate sites chosen for a Deep Underground Science and Engineering Laboratory (DUSEL) by NSF in 2005. In 2007 summer, NSF chose Homestake mine as their final DUSEL site. With this decision, our group decided to concentrate our research effort on T2K at least during the intense construction, installation, commissioning and initial data analysis period. We have been and will be making continuous intellectual contributions to the Next generation Nucleon decay and Neutrino detector (NNN) community through NNN workshop series that Jung founded in 1999 and other international discussions.

The NN group was originally established with Jung's DOE OJI award. The group joined SuperK in 1991 and became the leading US group for K2K which used SuperK as the far detector. After a successful run of K2K, we became involved in T2K as the leading US institution in the T2K US B280 (Beamline and ND280 detector) collaboration. T2K, which uses the neutrino beams produced at the J-PARC facility at Tokai, Japan and SuperK as the far detector, is a natural extension of K2K. The idea of UNO was first proposed by Jung in 1999 after the successful construction and operation of SuperK, based on the realization that a larger detector is needed to increase the sensitivity of proton decay searches and to study other neutrino physics topics.
