With the Large Hadron Collider in CERN performing beautifully, we are faced with a wealth of data that we hope will shed new light on the origin of electroweak symmetry breaking. The most urgent task is to find or exclude the only remaining unverified piece of the Standard Model, namely the Higgs boson. Over the past year, a particle that resembles the Higgs boson has been discovered at the laboratory. It will take some more time to verify its exact properties, but the discovery by itself is a wonderful event in fundamental science. Personally, I have participated in an experimental search for a variant of the standard Higgs boson and maintain an active interest in the theoretical and experimental problems involved.
Going beyond the search for the Higgs boson, there are numerous theoretical problems as well as experimental discrepancies that strongly suggest particles and interactions beyond those described by the Standard Model. Accordingly, I draw motivation from both theory and experiment in the search for physics beyond the Standard Model. Recently, I have been particularly interested and actively worked on the possibility of additional force carriers, their theoretical description as well as their manifestation in high energy colliders and atomic physics experiments. With the Large Hadron Collider probing new energy scales, the next several years are bound to lead to great progress in particle physics and exciting new discoveries.
As part of an effort to look for new physics, I have suggested and worked on several new structures that could be searched for at the LHC. The effort of searching for them is largely an experimental problem, but I have tried to help by providing theoretical simulations of such events. The relevant pages are:
