We study the quantum stabilization of a cosmic string by a heavy fermion doublet in a reduced version of the standard model. We show that charged strings, obtained by populating fermionic bound state ...
Level Crossing Analysis of Cosmic Microwave Background Radiation: A method for detecting cosmic strings
Cosmic Microwave Background Radiation detecting cosmic strings
2010/12/27
In this paper we study the footprint of cosmic string as the topological defects in the very early universe on the cosmic microwave background radiation. We develop the method of level crossing analy...
Nonabelian Cosmic Strings from SO(3) Gauge Symmetry
SO(3) Gauge Symmetry nonabelian cosmic strings
2010/4/15
The nature of SO(3) breaking into its closed subgroups and the emergence of nonabelian cosmic strings are discussed. Relevance to GUT breaking and thereby to cosmology is pointed out. Classification o...
