About Pran Nath
Professor Nath is a theoretical physicist who has made contributions to the fields of high energy theory, and to theories of particle physics and gravity. He is co-author of the "first" supergravity theories and a co-author of the well known mSUGRA model which is under experimental tests at the Fermilab Tevatron and will be subject to test at the CERN Large Hadron Collider (LHC). The mSUGRA model and its extensions are currently the leading contenders for new physics beyond the Standard Model of Glashow, Weinberg and Salam, and of Gross, Politzer and Wilczek. While the Standard Model of the electro-weak and strong interactions is very successful, and consistent with existing experimental data, it has many intrinsic drawbacks. It contains a large number of arbitrary parameters, suffers from the so called hierarchy problem, i.e., that it is difficult to keep the various mass scales apart in the theory, and it has no unification with gravity. Super theories (i.e., theories using supersymmetry, such as supergravity and superstrings) have the potential of rectifying many of the shortcomings of the Standard Model.
