Recent results on vector-like quarks and excited fermions at CMS

TL;DR

This paper reports on CMS searches for vector-like quarks and excited fermions using the full Run 2 LHC data, setting exclusion limits as no new particles were observed beyond the Standard Model predictions.

Contribution

It provides the most recent exclusion limits on vector-like quarks and excited fermions based on the complete Run 2 dataset from the LHC.

Findings

No significant excess observed above Standard Model expectations.

Exclusion limits set at 95% confidence level for various models.

Results improve previous bounds on vector-like quarks and excited fermions.

Abstract

The most recent results on the searches for the vector-like quarks and excited fermions from the CMS Collaboration are presented. These results are based on the full Run 2 $\sqrt{s} = $13 TeV proton-proton collision data collected by the CMS Collaboration at the LHC from 2016 to 2018, which corresponds to an integrated luminosity of 138 fb$^{-1}$. No significant excess above the Standard Model expectation is observed. Exclusion limits are set at the 95% confidence level on various benchmark models.
