Neutrino Physics

      Neutrino Physics (Current) Neutrinos are nearly-massless microscopic particles that are produced in many nuclear and particle interactions. They are produced copiously in the fusion reactions that power the sun; the resulting flux of neutrinos incident on the earth may be used as a probe of the solar interior. Interactions involving neutrinos are also of interest in super-dense "neutron stars". Theoretical investigations have included studies of neutrinos in dense stellar environments and in vacuum, and have also focused on the origin of neutrino masses.  This work has been published in Physical Review D and in the proceedings of Neutrino '98.  Recent work has been funded by the National Science Foundation (NSF).
