In addition to the faculty profiles below, much more information about our group can be found at the High Energy Particle and Particle Astrophysics webpage. In 2012 the HEPPA program was designated as a Program of Research and Scholarly Excellence.

Neutrino interactions, exotic physics, and detector development Prof. Norm Buchanan

My research interests are primarily related to neutrino experiments. My group participates in measurements of neutrino interactions and searches for exotic physics using large detectors associated with neutrino experiments. I am a member of the NOvA experiment at Fermilab, which is making precise measurements of neutrino properties via the oscillation of muon neutrinos into electron neutrinos. Similar measurements have provided the first evidence of physics beyond the Standard Model. I am also involved in research and development of detector technologies to be used in the next generation of neutrino experiments, such as DUNE, that could provide an explanation for the matter-dominated nature of the universe.

Our group’s activities are primarily in connection with the Auger Collaboration, which is working towards an understanding of the nature and origin of the highest-energy cosmic rays. The project consists of two observatories, one of which is under development in southeastern Colorado.

Neutrinos Prof. Walter Toki

I am full time working on the T2K experiment which observed muon neutrinos, produced at the J-PARC accelerator, oscillate into electron neutrinos, detected 280 kilometers away in the Super Kamiokande detector in the Kamioka Mine in Japan. My recent work includes antineutrino cross section measurements and how to estimate CP violation significance in long baseline neutrino experiments. In the past I worked on e+e- collider experiments in the BaBar and the BES collaborations.

Neutrinos and Large Underground Detectors Prof. Robert Wilson

My primary research focus currently is the Tokai-to-Kamioka (T2K) neutrino oscillation experiment in Japan; in addition to data analysis, I have developed a light injection system for the pi-zero detector. In parallel with T2K, I am working to develop a next generation Long Baseline Neutrino Experiment (LBNE) in the US; and I collaborate with industry to investigate applications to High Energy Physics of novel solid-state photosensors.
