Research Field: Elementary Particle Experiment

Research Focus: origin of the mass of fundamental particles, neutrino oscillations and mass

Professor Roe works on the mini-BooNE experiment at Fermilab. This experiment searches for oscillations of muon neutrinos into electron neutrinos. A tentative signal for this oscillation was seen in a Los Alamos experiment and the present experiment will give a definitive test of this result. If these oscillations are present, they indicate that neutrinos have masses in the range to be a component of the dark matter in the universe. Furthermore, taking all the neutrino oscillation tests together, a positive result from mini-BooNE would imply a major extension of the Standard Model beyond the three presently known left-handed neutrinos and their Standard Model interactions. A positive result would then be a major modification of the Standard Model. Professor Roe’s group has responsibility for monitoring counters, for one of two software data analysis systems and for a beam Monte Carlo program.

Professor Roe is a Fellow of the American Physical Society.
