SUMMARY:Giorgio Gratta (Stanford) "Probing Gravity - and Other Forces - at Extreme Scales"
DESCRIPTION:The inverse square law of gravity has been empirically tested to various degrees for distances between <0.1mm to 1AU.   Outside this range very little is known and\, yet\, physics beyond the standard model may actually introduce new long-range forces that would be observed as anomalies in the 1/R^2 behavior of gravity.   I will discuss some new experiments designed to substantially advance our knowledge in this area\, at the two extremes of the distance range.  While the long distance regime would involve a deep space mission\, a new breed of experiments focusing on the micron regime is already taking data\, not only on gravitational interactions.

SUMMARY:Bharat Ratra (Kansas State U.) "Dark Energy: Constant or Time Variable? (...and other open questions)""
DESCRIPTION:Experiments and observations over the last two decades have persuaded cosmologists that (as yet undetected) dark energy is by far the main component of the energy budget of the universe. I review a few simple dark energy models and compare their predictions to observational data\, to derive dark energy model-parameter constraints and to test consistency of different data sets. I conclude with a list of open cosmological questions.

SUMMARY:Prof. V.M. Datar (Tata Institute of Fundamental Research\, Mumbai\, India) "The India based Neutrino Observatory project"
DESCRIPTION:Abstract:\nThe Indian effort to build an underground laboratory for rare processes is outlined. The flagship experiment\, based on the 50 kiloton Iron Calorimeter\, will measure atmospheric muon neutrinos and antineutrinos\, separately\, and will target the open problem of the neutrino mass hierarchy. Together with other experiments worldwide this will help address CP violation in the neutrino sector and this may help us understand why there is a preponderance of matter over anti-matter in the universe. The other experiments that are being planned are in the areas of: (1) neutrinoless double beta decay using a cryogenic bolometer of 124Sn (2) dark matter search and (3) a low energy accelerator for measuring nuclear cross sections of astrophysical interest.
