Projective Modules and the Quillen Suslin Theorem
The notion of a module over a ring is a generalization of that of a vector space over a field k. The axioms are identical. But whereas every vector space possesses a basis, a module need not always have one. Modules ... -
Prolate Shaped Dark Matter Halo And The Galactic Warp
(2016-04-26)The physical explanation for the existence of the galactic warp is one of the major research areas in Astronomy. People have proposed various theories but nobody has yet given a convincing explanation. Most of the spiral ... -
Prompt and Displaced Signatures of Physics Beyond the Standard Model
The quest to understand our Universe’s fundamental particles and their interactions has led us to the Standard Model (SM) of particle physics. Despite successfully explaining the weak, electromagnetic, and strong ... -
Property Modulation Of Zinc Oxide Through Doping
(2009-04-24)Semi conductors are of technological importance and attracted many of the re-searchers. ZnO belongs to the family of II-VI semiconductors and has material properties well suitable to UV light emitters, varistors, Schottky ... -
Proposals for probing BSM in unexplored corners of Top physics and Next-to-Minimal Supersymmetric Standard Model (NMSSM)
Despite its triumphs, the Standard Model (SM) fails to address many experimental observations and theoretical puzzles. Explanation of these necessitates postulation of new physics beyond those in the SM (BSM). The thesis ... -
