Compatibility of muon g − 2, W mass anomaly in type-X 2HDM

چکیده

Recently CDF II Collaboration reported that they measured W boson mass precisely. The measurement is deviated from the Standard Model (SM) Prediction at 7σ. Also, recent FNAL of muon magnetic moment shows a 4.2σ deviation. To resolve as well (g−2) anomalies, we explore type-X two Higgs doublet model (2HDM). We analyze (mA,tan⁡β) parameter space 2HDM consistent with (g−2), lepton universality test and measurements collaboration. find h→AA branching ratio gives strong lower bound on mH.

Triangle Anomaly and the Muon G − 2 *

The subject of this paper is a class of two-loop electroweak contributions to the muon g−2 containing a fermion triangle along with a virtual photon and Z boson, as shown in Fig. 1. In the standard model all charged fermions contribute to the triangle loop. Individual contributions of fermions lighter than the Z boson are enhanced by large logarithms ln(MZ/m), where m denotes the mass of the fe...

Testing 2HDM at Muon Colliders

One very light neutral Higgs scalar with mass, say, below 40-50 GeV is still allowed in the non-supersymmetric 2HDM (Model II), while the remaining particles of the Higgs sector in this model have to be heavier. The possibility of testing such a scenario at Muon Colliders is discussed.

Muon ( g − 2 )

For a spin1 2 particle, ~ S = ~2~σ, and gs is called the Lande g-factor. From classical calculations that treat the charged particle as a rotating piece of current, gs = 1. Surprisingly, the Dirac equation in relativistic quantum mechanics predicts that gs = 2, a result which agreed with the crude experiments of the time. In the 1940’s, a new understanding of renormalization in the developing q...

Recent Muon g − 2 Result in Deflected Anomaly - Mediated Supersymmetry Breaking

We study the deflected anomaly-mediated supersymmetry breaking (AMSB) scenario in the light of the recent result of the muon g − 2 from Brookhaven E821 experiment. The E821 result suggests the deviation from the SM prediction, though there remain unsettled uncertainties. We find that the supersymmetric contribution to the muon g − 2 can be O(10), large enough to fill the deviation, with other e...

The muon (g - 2) anomaly and a new light vector boson

This mini review aims to outline the main experimental and theoretical results related with the search for a new light vector boson proposed as a solution of the muon g− 2 anomaly. Additionally, I consider a model with infinite number of light vector bosons which can explain the anomaly, while still remaining consistent with current experimental bounds. 1 ar X iv :1 70 2. 04 59 6v 1 [ he pph ] ...
