Model Parameter Reconstruction of Electroweak Phase Transition with TianQin and LISA: Insights from the Dimension-Six Model
Aidi Yang, Chikako Idegawa, Fa Peng Huang
We investigate the capability of TianQin and LISA to reconstruct the model parameters in the Lagrangian of new physics scenarios that can generate an electroweak SFOPT. Taking the…

Primordial Black Hole Formation and Multimessenger Signals in a Complex Singlet Extension of the Standard Model
Fa Peng Huang, Chikako Idegawa, Aidi Yang
We investigate the formation of primordial black holes (PBHs) induced by a first-order electroweak phase transition in a realistic renormalizable framework, the complex singlet ext…
