Theme Group 2

More Details on Future Plans

- Future Research
- Understanding neutrino masses and its connection to grand unification.
- Origin and nature of supersymmetry breaking and Higgs physics.
- Connecting superstring ideas to unify forces and matter and a better understanding of the nature of gravity.
- LHC physics e.g. Higgs bosons, SUSY and extra dimensions.
- Experimental efforts that complement these activities: e.g. (i) Babar and future B-physics activity, (ii) HE experimental group part of LHC collaboration, (iii)Astro-particle involvement in Ice Cube can elucidate the nature of neutrinos, (iv) Search for new long range forces in Nature, (iv) Nucl. Expt. Search for neutrino people for junior faculty.
- Continue to explore fundamental formal questions on the foundations

of supersymmetry, supergravity and superstring/M-theory with special emphasis on mathematical topics such as K-theory and representation theory.
