Higgs and Electroweak I
- Tyler Corbett (University of Vienna)
The Standard Model and Higgs Effective Field Theories (SMEFT and HEFT) are the two well-established theoretical frameworks for the parameterization of potential new physics signals from nearly decoupled BSM sectors. They differ in the scalar field content and - most notably - in the power counting, i.e. the way they organize BSM effects into a series expansion. While it's clear that in SMEFT...
I will present the basis of dimension-eight operators associated with universal theories. Without imposing C nor P the universality assumption reduces the number of independent SMEFT operators at dimension eight from 44807 to 175. 89 of the 175 universal operators are included in the general dimension-eight operator basis in the literature. The 86 additional operators involve higher...
The contribution will report on recent results on global EFT fits of the CMS data, with particular focus on a dimension-6 SMEFT interpretation of the measurements performed in the electroweak sector of the Standard Model, including results built upon likelihoods constructed from reconstructed-level information and properly including all correlations among the various input channels.
