We investigate the potential for observing gravitational waves from cosmological phase transitions with LISA in light of recent theoretical and experimental developments. Our analysis is based on current state-of-the-art simulations of sound waves in the cosmic fluid after the phase transition completes. We discuss the various sources of gravitational radiation, the underlying parameters describing the phase transition and a variety of viable particle physics models in this context, clarifying common misconceptions that appear in the literature and identifying open questions requiring future study. We also present a web-based tool, PTPlot, that allows users to obtain up-to-date detection prospects for a given set of phase transition parameters at LISA.

“…For example, it could detect the SGWB from a phase transition featuring k B T * = 100 GeV, β/H * = 500, v w = 0.7c, α = 0.07, where α denotes the strength of the phase transition, given by the ratio between the vacuum energy density and the radiation energy density in the universe at the transition time. These are typical parameters in scenarios whereby the Standard Model is extended with an extra singlet [118,158,234] or embedded in supersymmetry [89,142,170,205]. Hence DOs have the sensitivity to discover SGWBs indicating BSM physics.…”

The gravitational-wave astronomical revolution began in 2015 with LIGO's observation of the coalescence of two stellar-mass black holes. Over the coming decades, ground-based detectors like LIGO will extend their reach, discovering thousands of stellar-mass binaries. In the 2030s, the space-based LISA will enable gravitational-wave observations of the massive black holes in galactic centres. Between LISA and groundbased observatories lies the unexplored decihertz gravitational-wave frequency band. Here, we propose a Decihertz Observatory to cover this band, and complement observations made by other gravitational-wave observatories. The decihertz band is uniquely suited to observation of intermediate-mass (∼ 10 2-10 4 M) black holes, which may form the missing link between stellar-mass and massive black holes, offering a unique opportunity to measure their properties. Decihertz observations will be able to detect stellar-mass binaries days to years before they merge and are observed by ground-based detectors, providing early warning of nearby binary neutron star mergers, and enabling measurements of the eccentricity of binary black holes, providing revealing insights into their formation. Observing decihertz gravitational-waves also opens the possibility of testing fundamental physics in a new laboratory, permitting unique tests of general relativity and the Standard Model of particle physics. Overall, a Decihertz Observatory will answer key questions about how black holes form and evolve across cosmic time, open new avenues for multimessenger astronomy, and advance our understanding of gravitation, particle physics and cosmology.

“…The condition of the strong FOPT in the new physics beyond the SM can be more easily realized when the Higgs sector includes more scalars [52]. For example, there are works on a singlet extension of the SM [53][54][55][56] or more than one singlet extension [57][58][59][60], two-Higgs-doublet models (2HDMs) [61][62][63][64] or other doublet extensions [65,66], models with triplet extension [67], SUSY models [68][69][70][71], composite models [72][73][74] and walking technicolor models [75][76][77], twin Higgs models [78], Pati-Salam model [79,80], the left-right SU(4) model [81,82] motived by the B physics anomalies, Gorgi-Machacek model [83], axion or axion-like particle models [84][85][86], extra dimensional models [87], models with charged singlet [88], seesaw models [89], models with hidden sectors [90][91][92] and dark matter (DM) models [93][94]…”

The left-right symmetric model (LRSM) is a well-motivated framework to restore parity and implement seesaw mechanisms for the tiny neutrino masses at or above the TeV-scale, and has a very rich phenomenology at both the high-energy and high-precision frontiers. In this paper we examine the phase transition and resultant gravitational waves (GWs) in the minimal version of LRSM. Taking into account all the theoretical and experimental constraints on LRSM, we identify the parameter regions with strong first-order phase transition and detectable GWs in the future experiments. It turns out in a sizeable region of the parameter space, GWs can be generated in the phase transition with the strength of 10−17 to 10−12 at the frequency of 0.1 to 10 Hz, which can be detected by BBO and DECIGO. Furthermore, GWs in the LRSM favor a relatively light SU(2)R-breaking scalar $$ {H}_3^0 $$ H 3 0 , which is largely complementary to the direct searches of a long-lived neutral scalar at the high-energy colliders. It is found that the other heavy scalars and the right-handed neutrinos in the LRSM also play an important part for GW signal production in the phase transition.
