Analysis
This paper investigates the possibility of CP violation in an extension of the Standard Model with a Higgs triplet and a complex singlet scalar. The key finding is that spontaneous CP violation is strictly forbidden in the scalar sector of this model across the entire parameter space. This is due to phase alignment enforced by minimization conditions and global symmetries, leading to a real vacuum. The paper's significance lies in clarifying the CP-violating potential of this specific model.
Key Takeaways
- •The paper focuses on a Higgs Triplet Model extension.
- •It demonstrates the absence of spontaneous CP violation.
- •Phase alignment and global symmetries are key to the result.
- •The conclusion is that the scalar sector cannot source CP violation.
