  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 Z2 x Z2' symmetry. In this
model, all fields acquire a vacuum expectation value, such that the model
contains in total 3 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 builds on a whitepaper
submitted to the Snowmass process.
