A Hidden Strong Force Bent the Gravitational-Wave Spectrum
A modeled dark-QCD crossover adds a shifted distortion to scalar-induced gravitational waves.
Summary
A modeled dark-QCD crossover adds a shifted distortion to scalar-induced gravitational waves.
The calculation adds a confining dark sector, motivated by twin-Higgs and asymmetric dark-matter scenarios, to the thermal history used for scalar-induced gravitational waves. When an enhanced primordial mode re-enters near the dark confinement scale, the authors find an extra frequency-shifted feature above the ordinary QCD imprint. This is a theoretical signature under specified primordial and dark-sector assumptions, not a detection of dark QCD.
