Muon precession from the aspect of Dirac equations
Jinbo He, Lei Ming, Yi-Lei Tang +2
In this paper, we would like to compute the muon anomalous precession frequency through solving the wave functions of the Dirac equations straightforwardly. The precession of a (an…
Corrections to electroweak precision observables from mixings of an exotic vector boson in light of the CDF -mass anomaly
Chengfeng Cai, Dayun Qiu, Yi-Lei Tang +2
We enumerate various effective couplings that contribute to the mixings between an exotic vector boson and the neutral electroweak vector bosons. The miscellaneous mix…
