Description
We report on progress made on the CosWG2025-01 project, "Cosmic strings beyond minimally-coupled models". We consider the gravitational-wave background produced by strings with interactions beyond their coupling to gravity, examining several well-motivated extensions: metastable strings, superstrings, global strings, and strings moving in extra dimensions. We discuss LISA's ability to constrain the parameter space of these models based on simulations of signal recovery by SGWBinner. Finally, we comment on connections to beyond-standard-model physics and what theories could be probed by measurements of these string signals.
