1. Electroweak phase transition in the 2HDM: collider and gravitational wave complementarity

The knowledge of the Higgs potential is crucial for understanding the origin of mass and thermal history of our universe. We show how collider measurements and observations of stochastic gravitational wave signals can complement each other to explore the multiform scalar potential in the 2HDM. Accounting for theoretical and current experimental constraints, we analyze the key ingredients in...

9. Complex Singlet Benchmarks for Future Collider Scenarios

Introducing simplified models with new particles/symmetries is one of the simplest solutions to the questions unanswered by the Standard Model of particles physics. We explore the phenomenology of adding a complex scalar singlet to the Standard Model without imposing any additional symmetries. This extension is particularly interesting since the model has three scalar mass eigenstates. This...

16. 3HDM under $S_3$ Symmetry and Flavor Constraints

We investigate the scalar potential with soft breaking terms and flavor part of a general $S_3$-symmetric three-Higgs-doublet model. By assuming that the quarks, leptons and Higgs fields belong to irreducible representation of the permutation group $S_3$ and CP violation, parameter space that can reproduce quark masses, lepton masses, CKM matrix, PMNS matrix is obtained, which also satisfies...
