Education

  • Ph.D. Caltech 1971 (experimental high energy physics)
  • Ph.D. Thesis: Proton-antiproton annihilation into two charged meson final states between 0.7 and 2.4 GeV/c

Prof. Nicholson arrived at Mount Holyoke in 1971.

Current Research

Professor Nicholson works on a variety of projects with students depending on their interests.

For the past nine years I have been working with the BaBar collaboration at the Stanford Linear Accelerator. This collaboration consists of approximately 600 physicists and engineers. The primary purpose of the experiment is to study CP violation in B decays, but the experiment generates a lot of data, and charm mesons and tau mesons can also be studied. Currently I am looking for the tau neutrino mass limiting reaction tau decaying into charged kaon, K short and two pions which reconstruct to a mass close to the central value of the rho mass in the hope that we may be able to put more restrictive limits on the mass of the tau neutrino in direct decays.
