Primordial gravitational wave backgrounds from phase transitions with next generation ground based detectors

Chiara Caprini, Oriol Pujolà s, Hippolyte Quelquejay-Leclere +2

Third generation ground-based gravitational wave (GW) detectors, such as Einstein Telescope and Cosmic Explorer, will operate in the $(\text{few}-10^4)$ Hz frequency band, with a b…
