“…That is to say that the major contribution of physical fields H ± , A and H ±± comes from triplet fields, and the major contribution of physical fields h 1 , h 2 , h 3 and J comes from doublet and singlet fields. We use the general expressions presented in [68][69][70][71]. Approximative contributions of new scalar fields to S and T parameters in the 123-model are then given by:…”

Following the recent update measurement of the W boson mass performed by the CDF-II experiment at Fermilab which indicates 7σ deviation from the SM prediction. As a consequence, the open question is whether there are extensions of the SM that can carry such a remarkable deviation or what phenomenological repercussions this has. In this paper, we investigate what the theoretical constraints reveal about the 123-model. Also, we study the consistency of a CDF W boson mass measurement with the 123-model expectations, taking into account theoretical and experimental constraints. Both fit results of S and T parameters before and after m CDF W measurement are, moreover, considered in this study. Under these conditions, we found that the 123-model prediction is consistent with the measured m CDF W at a 95% Confidence Level (CL).

“…and the functions F , ξ and Ĝ can be found in Refs [68,69]. Note that, the precise measurements of the electroweak precision observables, such as the W and Z boson masses and the electroweak mixing angle, are used to determine the values of the S and T parameters.…”

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 Z2⊗Z2′ 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.
