Testing SUGRA Models
Utpal Chattopadhyay
A brief review is given of the ways of testing SUGRA unified models and a class of string models using data from precision electroweak experiments, Yukawa unification constraints,…

Upper limits on sparticle masses from WMAP dark matter constraints with modular invariant soft breaking
Utpal Chattopadhyay, Pran Nath
An analysis of dark matter within the framework of modular invariant soft breaking is given. In such scenarios inclusion of the radiative electroweak symmetry breaking constraint d…

Modular Invariant Soft Breaking, WMAP, Dark Matter and Sparticle Mass Limits
Utpal Chattopadhyay, Pran Nath
An analysis of soft breaking under the constraint of modular invariance is given. The role of dilaton and moduli dependent front factors in achieving a modular invariant …
