Description
Future gravitational-wave detectors can probe primordial non-Gaussianity and parity violation through the stochastic gravitational-wave background. In this talk, I will present a framework that includes both parity-even and parity-odd higher-order correlators. Using simulated data for next-generation detectors, like Einstein Telescope and Cosmic Explorer, I will demonstrate that these effects can be constrained even in the presence of an astrophysical foreground. The parity-odd component, in particular, leads to a circularly polarized signal, providing a direct probe of chirality in the early Universe.
Finally, I will discuss how this framework can be extended to space-based detectors such as LISA, enabling a synergic detection across complementary frequency bands.
