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…
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…
Distinguishing Dirac from Majorana Heavy Neutrino at Future Lepton Colliders
Qing-Hong Cao, Kun Cheng, Yandong Liu
We propose to identify whether a sterile neutrino is Dirac-type or Majorana-type by counting the peak of the rapidity distribution at lepton colliders. Our method requires only one…
Measuring Coupling at Lepton Colliders
Qing-Hong Cao, Kun Cheng, Yandong Liu +1
The quartic Higgs-gauge-boson coupling is sensitive to the electroweak symmetry breaking mechanism, however, it is challenging to be measured at the large hadron collide…
Unitarity Bounds and Basis Transformations in SMEFT: An Analysis of Warsaw and SILH Bases
Qing-Hong Cao, Yandong Liu, Shu-Run Yuan
The equivalence between the Warsaw and SILH bases in Standard Model Effective Field Theory is well established, with transformation rules connecting the two via equations of motion…
Exposing new scalars hiding behind the Higgs boson
Qing-Hong Cao, Kun Cheng, Yandong Liu +3
It is possible that there is another scalar hiding behind the known 125 GeV Higgs boson. If the hidden scalar exhibits a CP property different from the Higgs boson, it can be expos…

Qing-Hong Cao, Hao-Ran Jiang, Bin Li +2
The magnetic moment () and weak magnetic moment () of charged leptons and quarks are sensitive to quantum effects of new physics heavy resonances. In effective field theo…

We present a comprehensive analysis of the loop induced top quark FCNC signals at the LHC within one class of the simplified model. The loop level FCNC interactions are well motiva…
What can We Learn from Triple Top-Quark Production?
Qing-Hong Cao, Shao-Long Chen, Yandong Liu +1
Different from other multiple top-quark productions, triple top-quark production requires the presence of both flavor violating neutral interaction and flavor conserving neutral in…

Qing-Hong Cao, Shao-Long Chen, Yandong Liu +2
We demonstrate that the multi-top productions efficiently probe the CP-property of top-Higgs interaction and the Higgs-boson width at the LHC. The four top-quark production alone c…

A Boost Test of Anomalous Diphoton Resonance at the LHC
Qing-Hong Cao, Yandong Liu, Ke-Pan Xie +2
The recently observed diphoton resonance around 750~GeV at the LHC Run-2 could be interpreted as a weak singlet scalar. The scalar might also decay into a pair of -boson and pho…
The Diphoton Excess, Low Energy Theorem and the 331 Model
