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…
New observables for testing Bell inequalities in boson pair production
Qi Bi, Qing-Hong Cao, Kun Cheng +1
We show that testing Bell inequalities in pair systems by measuring their angular correlation suffers from the ambiguity in kinetical reconstruction of the di-lepton decay…
Global Symmetries and Effective Potential of 2HDM in Orbit Space
Qing-Hong Cao, Kun Cheng, Changlong Xu
We extend the framework of analyzing the 2HDM in its orbit space to study the one-loop effective potential before and after electroweak symmetry breaking. In this framework, we pre…
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…
CP Phases in 2HDM and Effective Potential: A Geometrical View
Qing-Hong Cao, Kun Cheng, Changlong Xu
Using a geometric description of 2HDM, we classify CP invariants into three independent sectors such as scalar potential, Yukawa interaction and CKM matrix. Thermal effective poten…
