Constraining the real singlet extension of the Standard Model: implications for vacuum stability
Moritz Bosse, Gudrun Hiller, Daniel Litim +4
The paper investigates the addition of a real singlet scalar to the Standard Model, analyzing theoretical and experimental constraints and its impact on electroweak phase transitio…
Constraining the real scalar singlet extension of the SM
Moritz Bosse, Gudrun Hiller, Daniel Litim +4
The real scalar singlet extension of the standard model provides a minimal framework in which the Higgs sector can realise a strong first-order electroweak phase transition and imp…
Bubble wall velocity from Kadanoff-Baym equations: fluid dynamics and microscopic interactions
Michael J. Ramsey-Musolf, Jiang Zhu
We establish a first principles, systematic framework for determining the bubble wall velocity during a first order cosmological phase transition. This framework, based on non-loca…
Does the Electron EDM Preclude Electroweak Baryogenesis ?
Yuan-Zhen Li, Michael J. Ramsey-Musolf, Jiang-Hao Yu
Electroweak baryogenesis (EWBG) constitutes a theoretically compelling and experimentally testable mechanism for explaining the origin of the baryon asymmetry of the universe (BAU)…
Probing scalar-neutrino and scalar-dark-matter interactions with PandaX-4T
PandaX Collaboration, Tao Li, Zihao Bo +113
Scalar-mediated interactions may exist among neutrinos, dark matter particles, or between the two. Double -decay experiments provide a powerful tool to probe such exotic intera…
Dissecting Lepton Number Violating Interactions in the Left-Right Symmetric Model: decay, Møller scattering, and collider searches
Gang Li, Michael J. Ramsey-Musolf, Sebastián Urrutia Quiroga +1
In the context of the left-right symmetric model, we study the interplay of neutrinoless double beta () decay, parity-violating Møller scattering, and high-energy collide…
