First-order phase transition and fate of false vacuum remnants
Kiyoharu Kawana, Philip Lu, Ke-Pan Xie
False vacuum remnants in first-order phase transitions in the early Universe can form compact objects which may constitute dark matter. Such remnants form because particles develop…
Leptogenesis triggered by a first-order phase transition
Peisi Huang, Ke-Pan Xie
We propose a new scenario of leptogenesis, which is triggered by a first-order phase transition (FOPT). The right-handed neutrinos (RHNs) are massless in the old vacuum, while they…
Classification of Abelian domain walls
Yongcheng Wu, Ke-Pan Xie, Ye-Ling Zhou
We discuss domain walls from spontaneous breaking of Abelian discrete symmetries . A series of different domain wall structures are predicted, depending on the symmetry and ch…
Collapsing domain walls beyond
Yongcheng Wu, Ke-Pan Xie, Ye-Ling Zhou
Discrete symmetries are widely imposed in particle theories. It is well-known that the spontaneous breaking of discrete symmetries leads to domain walls. Current studies of domain…
Cosmological phase transitions, gravitational waves and self-interacting dark matter in the singlet extension of MSSM
Wenyu Wang, Ke-Pan Xie, Wu-Long Xu +1
In the minimal supersymmetric standard model (MSSM) extended by a singlet superfield, when the coupling between the singlet sector and the MSSM sector is tiny, the singlet sector c…
Probing the Electroweak Phase Transition with Exotic Higgs Decays
Marcela Carena, Jonathan Kozaczuk, Zhen Liu +5
An essential goal of the Higgs physics program at the LHC and beyond is to explore the nature of the Higgs potential and shed light on the mechanism of electroweak symmetry breakin…
Detection of Early-Universe Gravitational Wave Signatures and Fundamental Physics
Robert Caldwell, Yanou Cui, Huai-Ke Guo +34
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…
Heavy Neutral Lepton Searches at the Electron-Ion Collider: A Snowmass Whitepaper
Brian Batell, Tathagata Ghosh, Tao Han +1
In this whitepaper, we consider the model of heavy neutral leptons (HNLs) as an example to explore the potential of new physics searches at the Electron-Ion Collider (EIC). We prop…
Old Phase Remnants in First Order Phase Transitions
Philip Lu, Kiyoharu Kawana, Ke-Pan Xie
First order phase transitions (FOPTs) are usually described by the nucleation and expansion of new phase bubbles in the old phase background. While the dynamics of new phase bubble…
Primordial black holes from an electroweak phase transition
Peisi Huang, Ke-Pan Xie
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 Standard Model with…
