  • We present the first complete MCMC analysis of cosmological models with evolving cosmic (super)string networks, using the Unconnected Segment Model in the unequal-time correlator formalism. For ordinary cosmic string networks, we derive joint constraints on ΛCDM and string network parameters, namely the string tension Gμ, the loop-chopping efficiency cr and the string wiggliness α. For cosmic superstrings, we obtain joint constraints on the fundamental string tension GμF, the string coupling gs… CONTINUE READING
