CMB constraints on cosmic strings and superstrings

Year: 2016

Type: article

Abstract: The authors present the first complete Markov chain Monte Carlo analysis of cosmological models with $e\phantom{\rule{0}{0ex}}v\phantom{\rule{0}{0ex}}o\phantom{\rule{0}{0ex}}l\phantom{\rule{0}{0ex}}v\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}g$ cosmic string $a\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}d$ cosmic superstring networks, and derive constraints for parameters like the string tension, string coupling, effective volume of compact extra dimensions etc. The results are compared with other simulations like for Nambu-Goto strings and Abelian-Higgs strings, where available.
