Abstract

In this proceeding, I discuss several models that extend the scalar sector of the Standard Model by additional matter states. I here focus on results for models with singlet extensions, which have been obtained recently and update some of the results presented in previous work. In more detail, I will briefly review the option to test a strong first-order electroweak phase transition using precision measurements in the electroweak sector, as well as production cross-sections for non-standard scalar production at Higgs factories.

Notes

  1. 1.

    I thank D. Azevedo for providing exclusion limits for \(b\,\bar{b}\tau ^+\tau ^-\) [27] in a digitized format, as used in [28].

  2. 2.

    We include searches currently available via HiggsBounds.

  3. 3.

    This corresponds to the PDG value at the time of the above reference. The current value [39] is slightly lower. We do not expect this to have a qualitatively large impact.

  4. 4.

    At the order of perturbation theory discussed here; extending to higher orders might introduce additional parameter dependencies.

  5. 5.

    Note that the Run 2 combinations of ATLAS [41] and CMS [42] separately lead to \(|\sin \theta |\,\lesssim \,0.26\) and \(|\sin \theta |\,\lesssim \,0.33\), respectively.

  6. 6.

    The parameter scans include only current bounds, not possible discovery or exclusion at e.g. a HL-LHC.
