High-energy physics, strong and electroweak interactions

Brief C.V.

Research Activities

My research focuses on high-energy physics, in particular collider phyiscs. For the past few years, I have concentrated on di-boson production; that is, 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, located at Fermi National Accelerator Laboratory (Fermilab) about forty miles west of Chicago. The Tevatron collides protons and antiprotons at a center of mass energy of 1,800 GeV.

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 below.

More recently I have become interested in how electroweak radiative corrections and multiple photon radiation shift the experimentally measured W and Z boson masses, and how the couplings of the top quark can be measured at hadron colliders.
