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 …

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 …

Gravitational waves are a unique probe of the early Universe, as the Universe is transparent
to gravitational radiation right back to the end of inflation. This review summarizes detection …

A bstract We investigate a possible realization of pseudo-Nambu-Goldstone (pNG) dark
matter in the framework of a singlet-extended 2 Higgs doublet model (S2HDM). pNG dark …

We briefly survey several typical CP-conserving two-Higgs-doublet models (2HDMs) in light
of current experiments. First we derive the masses and couplings of the mass eigenstates …

A bstract Models of particle physics that feature phase transitions typically provide
predictions for stochastic gravitational wave signals at future detectors and such predictions …

We explore the gravitational wave spectrum generated by string-wall structures in an SO
(10)(S pin (10)) based scenario of pseudo-Goldstone boson dark matter (pGDM) particle …

We study stochastic gravitational waves from cosmic strings generated in an ultraviolet-
complete model for pseudo-Nambu-Goldstone dark matter with a hidden ${U (1)} $ gauge …

Abstract Pseudo-Nambu-Goldstone dark matter can interact with Standard Model fermion
through the Higgs portal, and some models can emerge a cancellation mechanism that …

A pseudo-Nambu-Goldstone boson (pNGB) is an attractive candidate for dark matter (DM)
due to the simple evasion of the current severe limits of DM direct detection experiments …
