engSHEN, XiaoheRecent results on Vector Like Quarks/Excited Fermions at CMSDetectors and Experimental TechniquesCMS-CR-2025-275The 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.2025-11-26http://cds.cern.ch/record/2950626http://cds.cern.ch/record/2950626oai:cds.cern.ch:2950626
