We investigate the reach of the LIGO/Virgo/KAGRA detectors in the search for signatures of first-order phase transitions in the early Universe. Utilising data from the first three observing runs, we derive constraints on the parameters of the underlying gravitational-wave background, focusing on transitions characterised by strong supercooling. As an application of our analysis, we determine bounds on the parameter space of two representative particle physics models. We also comment on the expected reach of third-generation detectors in probing supercooled phase transitions.

    hep-ph 2025-02 conditional novelty 6.0 of 10

    In Randall-Sundrum warped extra dimension models, the supercooled radion phase transition can form primordial black holes that account for all of dark matter for IR scales 10 TeV to 10^4 TeV, with correlated gravitati...

  2. A battle of designs: triangular vs. L-shaped detectors and parity violation in the gravitational-wave background

    gr-qc 2025-11 conditional novelty 4.0 of 10

    L-shaped Einstein Telescope designs outperform triangular designs for detecting a parity-violating gravitational-wave background, and ET alone cannot do it under current observational constraints.
