## TL;DR

This paper presents TopFitter, a comprehensive analysis fitting top-quark Wilson Coefficients using Run II LHC data and particle-level observables to test deviations from the Standard Model.

## Contribution

It introduces an updated TopFitter framework incorporating new LHC Run II data and particle-level observables for more precise Wilson Coefficient fitting.

## Key findings

- Improved constraints on top-quark Wilson Coefficients.
- Enhanced analysis with particle-level observables.
- Updated fit results using latest LHC data.

## Abstract

We describe the latest TopFitter analysis, which uses top quark observables to fit the Wilson Coefficients of the SM augmented with dimension-6 operators. In particular, we discuss the inclusion of new LHC Run II data and the implementation of particle-level observables.
