Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

Gravitational waves (GWs) were recently detected for the first time. This revolutionary
discovery opens a new way of learning about particle physics through GWs from first-order …

We undertake a careful analysis of stochastic gravitational wave production from
cosmological phase transitions in an expanding universe, studying both a standard radiation …

A bstract Gravitational waves (GWs) from strong first-order phase transitions (SFOPTs) in the
early Universe are a prime target for upcoming GW experiments. In this paper, I construct …

Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark
discovery, potentially providing a significant clue to some of our most basic, big-picture …

In the post-LIGO era, there has been a lot of focus on primordial black holes (PBHs) heavier
than∼ 10 15 g as potential dark matter (DM) candidates. We point out that the branch of the …

A bstract We study the possible gravitational wave signal and the viability of baryogenesis
arising from the electroweak phase transition in an extension of the Standard Model (SM) by …

A bstract We study the complementarity of the proposed multi-TeV muon colliders and the
near-future gravitational wave (GW) detectors to the first order electroweak phase transition …

We propose a mechanism that forms primordial black holes (PBHs) via a first-order
electroweak phase transition (FOEWPT). The FOEWPT is realized by extending the …

This study explores the generation of the observed baryon asymmetry of the Universe within
the complex two-Higgs doublet model (C2HDM) while considering theoretical and current …
