A two Higgs doublet model explains both the W-boson mass anomaly and the muon (g-2) anomaly. This requires specific mass differences in Higgs bosons, testable at the Large Hadron Collider (LHC).
Area of Science:
- High Energy Physics
- Particle Physics
- Beyond the Standard Model Physics
Background:
- Recent CDF Collaboration measurements show a high-precision W-boson mass.
- The muon anomalous magnetic dipole moment (g-2) presents a persistent anomaly.
Purpose of the Study:
- To investigate the correlation between the W-boson mass anomaly and the muon (g-2) anomaly.
- To explore explanations within the two Higgs doublet model framework.
Main Methods:
- Analysis of one-loop diagrams involving neutral scalar boson exchange.
- Investigating mass splitting requirements within the second Higgs doublet.
- Exploring collider signatures at the Large Hadron Collider (LHC).
Main Results:
- A correlation is found between the W-boson mass and muon (g-2) anomalies in the two Higgs doublet model.
- Significant mass splittings among Higgs bosons are required for simultaneous explanation.
- The model predicts constraints on scalar boson masses (< 600 GeV).
Conclusions:
- The two Higgs doublet model offers a potential explanation for both anomalies.
- Specific collider signatures, such as same-sign dimuon events at the LHC, can test this model's parameter space.
