B-L Cosmic strings and Baryogenesis
Pijushpani Bhattacharjee, Narendra Sahu, U. A. Yajnik
Cosmic strings arising from breaking of the gauge symmetry that occurs in a wide variety of unified models can carry zero modes of heavy Majorana neutrinos. Decaying a…
Fractionally charged extended objects and superselection rules
Narendra Sahu, Urjit A. Yajnik
Topological objects resulting from symmetry breakdown may be either stable or metastable depending on the pattern of symmetry breaking. However, if they trap zero-energy modes of f…
Inflation with bulk fields in the Randall-Sundrum warped compactification?
J. M. Cline, U. A. Yajnik
Randall and Sundrum have proposed that we live on a brane embedded in 5-dimensional anti-deSitter space, as a solution to the hierarchy problem. We examine the possibility of using…
Baryogenesis through axion domain wall
S. N. Nayak, U. A. Yajnik
Generic axion models give rise to axion domain walls in the early Universe and they have to disappear not to overclose the universe, thus limiting the nature of discrete symmetry a…
Supersymmetry : A new organizing principle for the microworld?
U. A. Yajnik
A glorious achievement of twentieth century Physics is the identification of the building blocks of nature. A related triumph a deep understanding of the forces of interaction. In…
