Particle Physics and Astrophysics
In addition to other links below, you may be interested in looking at the High Energy Physics group homepage, which offers an entry point to all of the activities in high energy particle physics and astrophysics at Colorado State.
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.
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.
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.
Neutrinos, Next-Geneneration Electron-Positron Collider, 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 preparing for data analysis, I am developing a light injection system for the pi-zero detector. In parallel with this work, I am developing an R&D proposal and investigating the physics potential of a future very large Underground Nucleon Decay and Neutrino Oscillation (UNO) experiment; evaluating new detector technologies for a future high energy Linear Collider; and I am working with industry to investigate applications to High Energy Physics of novel solid-state photosensors.
