Probing High-Quality Axions with Gravitational Waves
Ruiyu Zhou, Jin-Wei Wang, Ligong Bian
We present a systematic study of gravitational wave (GW) signals from phase transitions and topological defects in a unified high-quality axion framework. The gauged symme…
Gravitational waves and dark matter with Witten effect
Ruiyu Zhou, Ligong Bian
We investigate the breaking of dark symmetry at different temperature scales, occurring after Peccei-Quinn symmetry breaking or following QCD symmetry breaking. We focus…
Gravitational waves and monopoles dark matter from first-order phase transition
Jing Yang, Ruiyu Zhou, Ligong Bian
We study the possibility of monopoles serving as dark matter when they are produced during the first-order phase transition in the dark sector. Our study shows that dark monopoles…
Electroweak Phase Transition and Gravitational Waves in the Type-II Seesaw Model
Ruiyu Zhou, Ligong Bian, Yong Du
The type-II seesaw model is a possible candidate for simultaneously explaining non-vanishing neutrino masses and the observed baryon asymmetry of the Universe. In this work, we stu…
FIMP dark matter mediated by massive gauge boson around the phase transition period and the gravitational waves production
Ligong Bian, Yi-Lei Tang, Ruiyu Zhou
We study the feebly interacting massive particle dark matter whose production processes are significantly affected by the phase evolution and the complicated thermal corrections to…
Probing new physics for and gravitational waves
Ruiyu Zhou, Ligong Bian, Jing Shu
We study the possibility of probing new physics accounting for anomaly and gravitational waves with pulsar timing array measurements. The model we consider is either a li…
Heavy dark matter and Gravitational waves
Xin Deng, Xuewen Liu, Jing Yang +2
Domain walls can form after breakdown of a discrete symmetry induced by first-order phase transition, we study the heavy dark matter produced around the temperature of the phase tr…
Gravitational waves from cosmic strings and first-order phase transition
Ruiyu Zhou, Ligong Bian
Cosmic strings and first-order phase transition are two main sources for the stochastic gravitational wave background (SGWB). In this work, we study the stochastic gravitational wa…
Gravitational Waves from first-order phase transition and domain wall
Ruiyu Zhou, Jing Yang, Ligong Bian
In many particle physics models, domain wall can form during the phase transition process after discrete symmetry breaking. We study the scenario within a complex singlet extended…
Gravitational wave and electroweak baryogenesis with two Higgs doublet models
Ruiyu Zhou, Ligong Bian
We study stochastic gravitational wave production and baryon number generation at electroweak phase transition with the two Higgs doublet models. The produced stochastic gravitatio…

Ruiyu Zhou, Ligong Bian, Huai-Ke Guo
We present the relation between the sphaleron energy and the gravitational wave signals from a first order electroweak phase transition. The crucial ingredient is the scaling law b…
Gravitational wave and Collider searches for the EWSB patterns
Ligong Bian, Huai-Ke Guo, Yongcheng Wu +1
We study the Electroweak symmetry breaking mechanism with extra Electroweak symmetry breaking contributions (eEWSB) that are bounded by the Fermi constant and limits from the relat…
Electroweak phase transition and Higgs phenomenology in the Georgi-Machacek model
Ruiyu Zhou, Wei Cheng, Xin Deng +2
In this work, we perform the electroweak phase transition study with the Georgi-Machacek model. We investigate both the one-step and two-step strong first order electroweak phase t…
