T2K near detector during magnet closing Accelerator-based neutrino physics    Prof. Norm Buchanan

My research interests are primarily related to neutrino experiments that utilize accelerator driven beams of neutrinos. I am a member of the T2K experiment in Japan, 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 LBNE, that could provide an explanation for the matter-dominated nature of the universe.


Super Kamiokande detector being cleaned Ultra-High-Energy Cosmic Rays    Prof. John Harton

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.


Miguel Mostafa at Auger South Particle Astrophysics    Prof. Miguel Mostafa

Our group has been studying the spectrum, composition, and sources of the highest energy particles in the Universe. We are presently working with data from the largest cosmic ray detector currently in operation: the Pierre Auger Observatory. We are working on several publications regarding the time synchronization of the detectors, telescope alignment, elongation rate, angular calibration of the Observatory, and anisotropy studies at low energy using hybrid events.


Blue Laser B-mesons, charmonium states, and neutrinos Prof. Walter Toki

My research group focused on the analysis of B mesons and charmonium states produced in the BaBar detector at the PEPII collider at the Stanford Linear Accelerator Center. Recently I have joined the T2K experiment which will search for the oscillation of muon neutrinos, produced from the J-PARC accelerator, into electron neutrinos, detected 280 kilometers away in the Super Kamiokande detector in the Kamioka Mine in Japan.


Wilson under the P0D at J-PARC 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.
