Probing CP Violation through Vector Boson Fusion at High-Energy Muon Colliders
Qing-Hong Cao, Jian-Nan Ding, Yandong Liu +1
We investigate CP-violating effects in electroweak interactions at future high-energy muon colliders within the Standard Model Effective Field Theory (SMEFT) framework. Focusing on…
First Constraint on Axion-Photon Coupling from Neutron Star Observations
Jun-Chen Wang, Shunshun Cao, Jinchen Jiang +3
We propose a novel method to detect axions which uniquely depends on the dimensionless axion-photon coupling , independent of the suppressive axion decay constant . Using…
Can we live in a baby universe formed by a delayed first-order phase transition?
Qing-Hong Cao, Masanori Tanaka, Jun-Chen Wang +2
We examine the idea that our universe began as a baby universe and show that this is feasible in a gauged extension of the Standard Model with the classically conforma…
Berry phase in axion physics, SM global structure, and generalized symmetries
Qing-Hong Cao, Shuailiang Ge, Yandong Liu +1
We investigate the Berry phase arising from axion-photon and axion-fermion interactions. The effective Hamiltonians in both systems share the same form, enabling a unified descript…
