The researchers used realistic equations of state and first-principle quantum chromodynamic calculations for the first time to find the structure of mirror neutron stars, enabling them to predict gravitational wave signals and demonstrate the ability to explore dark sectors connected to the hierarchy problem.
The fundamental nature of dark matter is entirely unknown. A compelling candidate is twin Higgs mirror matter, invisible hidden-sector cousins of the Standard Model particles and forces. This predicts mirror neutron stars made entirely of mirror nuclear matter. We find their structure using realistic equations of state, robustly modified based on first-principle quantum chromodynamic calculations, for the first time. This allows us to predict their gravitational wave signals, demonstrating an impressive discovery potential and ability to probe dark sectors connected to the hierarchy problem.
