Two-Real-Singlet-Model Benchmark Planes

In this manuscript, I briefly review the Benchmark Planes in the Two-Real-Singlet Model (TRSM), a model that enhances the Standard Model (SM) scalar sector by two real singlets that obey a Z(2)circle times Z '(2) symmetry. In this model, all fields acquire a vacuum expectation value, such that the model contains in total three CP-even neutral scalars that can interact with each other. All interactions with SM-like particles are inherited from the SM-like doublet via mixing. I remind the readers of the previously proposed benchmark planes and briefly discuss possible production at future Higgs factories, as well as regions in a more generic scan of the model. For these, I also discuss the use of the W-boson mass as a precision observable to determine allowed/excluded regions in the models' parameter space. This work is an extension of a white paper submitted to the Snowmass process.

Automated summary

In this manuscript, I provide a brief review of the Benchmark Planes in the Two-Real-Singlet Model (TRSM), which enhances the scalar sector of the Standard Model (SM) by introducing two real singlets with Z(2)circle times Z'(2) symmetry. The model includes three CP-even neutral scalars that can interact with each other, where the interactions with SM-like particles are derived from mixing with the SM-like doublet. I discuss the previously proposed benchmark planes and explore the possibilities of production at future Higgs factories, as well as examine different regions in a more general scan of the model. Additionally, I investigate the use of the W-boson mass as a precision observable to determine allowed/excluded regions in the parameter space of the model. This work is an extension of a white paper submitted to the Snowmass process.
