Cosmic Superstrings Revisited in Light of NANOGrav 15-Year Data

Published 29 Jun 2023 in astro-ph.CO, astro-ph.HE, gr-qc, hep-ph, and hep-th | (2306.17147v2)

Abstract: We analyze cosmic superstring models in light of NANOGrav 15-year pulsar timing data. A good fit is found for a string tension $G \mu \sim 10{-12} - 10{-11}$ and a string intercommutation probability $p \sim 10{-3} - 10{-1}$. Extrapolation to higher frequencies assuming standard Big Bang cosmology is compatible at the 68\% CL with the current LIGO/Virgo/KAGRA upper limit on a stochastic gravitational wave background in the 10 to 100 Hz range. The superstring interpretation of the NANOGrav data would be robustly testable by future experiments even in modified cosmological scenarios.
