Combined EFT interpretation of top quark, Higgs boson, electroweak and QCD measurements at CMS

TL;DR

This paper presents a comprehensive Effective Field Theory analysis combining multiple measurements from CMS and other experiments to constrain 64 Wilson Coefficients across top, Higgs, electroweak, and QCD sectors.

Contribution

It introduces a combined EFT framework integrating diverse measurements, including electroweak precision observables, to improve sensitivity to new physics effects.

Findings

Constraints on 64 Wilson Coefficients are obtained.

Simultaneous fit to 42 linear combinations enhances sensitivity.

Integration of LEP, SLC, and CMS data provides comprehensive EFT constraints.

Abstract

A recent EFT result from CMS is presented, combining differential cross section and direct EFT measurements performed by the CMS Collaboration across four branches of the Standard Model: top, Higgs, electroweak and QCD physics. To maximize the sensitivity, measurements of electroweak precision observables from LEP and SLC are included as well. 64 Wilson Coefficients (WC) are targeted in this combined measurement, both individually and with a simultaneous fit to 42 linear combinations of the Wilson Coefficients.
