The $s$-channel resonant production of the Higgs boson at a 125 GeV muon collider enables a unique way to determine the Higgs properties. However, a clear picture of the achievable Higgs precision has not yet been established. We perform a phenomenological study of the Higgs measurements at such resonant muon collider Higgs factory and present a systematic, detailed, and consistent extraction...

We present a study of Higgs boson production in vector boson fusion and in association with a vector boson and its decay to two vector bosons, with a focus on the treatment of virtual loops and virtual photons. Our analysis is performed with the JHU generator framework, and the results are expressed in terms of an effective field theory. New features of this study include a proposal on how to...

We present results for the achievable sensitivity to Higgs properties via single Higgs production at future muon colliders. All relevant decay channels for on-shell Higgs production are analysed including physics backgrounds using fast simulation for a comprehensive picture of the expected precision. We additionally show results where we include some effects of the muon collider specific Beam...

Some supersymmetric extensions to the standard model such as the two-Higgs doublet model (2HDM) predict the decay of the Higgs boson to two pseudoscalar particles (H-->aa), each of which may decay into low-pT bottom quarks. We conduct a sensitivity study with simulated events for the H-->aa-->4b decay, in which the SM Higgs is produced by Vector Boson Fusion with an associated photon (VBF+photon).

In the Standard Model, the ground state of the Higgs field is not found at zero but instead corresponds to one of the degenerate solutions minimising the Higgs potential. In turn, this spontaneous electroweak symmetry breaking provides a mechanism for the mass generation of nearly all fundamental particles. The Standard Model makes a definite prediction for the Higgs boson self-coupling and...

The discovery of the Higgs boson with the mass of about 125 GeV completed the particle content predicted by the Standard Model. Even though this model is well established and consistent with many measurements, it is not capable to solely explain some observations. Many extensions of the Standard Model addressing such shortcomings introduce additional Higgs-like bosons which can be either...

Studies of the CP properties of the Higgs boson in various production modes and decay channels are presented. Limits on the mixing of CP-even and CP-odd Higgs states are set by exploiting the properties of diverse final states.

The talk will detail recent differential measurements of Higgs boson production, including both fiducial and STXS measurements, with bb, tautau, gamma gamma, ZZ and WW decay modes, by the CMS collaboration. Focus will be put on analyses exploiting the full statistical power of LHCs Run 2
