Research Interests and achievement
Updated on September 3, 2006
The standard model (SM) of the strong and electroweak interaction has had enormous success in explaining all relevant existing experimental data. However, it is generally anticipated that there is new physics in higher energy regions. In addition to a large number of free parameters, the SM leaves too many questions un-answered. Why are there three families? What is the explanation for fermion masses in view of the tremendous range of their values? What is the origin of CP violation? The answers to these questions and many others lie beyond the SM. Although, to date, there are no disagreements between theory and experiment which might give us some clue as to what may lie beyond the SM, it is important to keep searching for discrepancies between the SM and experiment. The ongoing and the next generation of experiments may provide clues as to what form the new physics will take. Furthermore, theorists must continue to look for models which might give answers to some of the above questions, and which can be tested experimentally. My research interests are (1) to look for new ways of testing the SM, (2) to use experimental data to put limits on physics beyond the SM, and (3) to construct models of new physics, and to examine their experimental consequences.
