Research Interests

My research is focused on High Energy Physics, in particular Collider Physics. For the last few years I have concentrated on di-boson production, ie. the production of WZ, W-photon and Z-photon pairs (the W and Z bosons are the carriers of the weak force) at the Tevatron collider. The Tevatron collides protons and anti-protons at a center of mass energy of 1800 GeV and is located at Fermi National Accelerator Laboratory (Fermilab) about 40 miles west of Chicago. Di-boson production is interesting since it opens new ways to test the Glashow-Weinberg-Salam (GSW) model of electroweak interactions. The GSW model is based on a non-abelian gauge theory with gauge group SU(2)xU(1). Because of its gauge theory nature the GSW model exactly predicts the self-interactions of W and Z bosons, and photons, and these self-interactions can be tested in W and Z boson pair production. In a series of research papers, I have reported on calculations of these processes at leading order and next-to-leading order in perturbation theory. Monte Carlo event generators have been made available to experimenters which allow a realistic simulation of di-boson production in Tevatron experiments. A few of these papers are listed above. More recently I have become interested in how electroweak radiative corrections and multiple photon radiation shift the experimentally measured W and Z boson masses.
