Searches for New Physics in Multijet Final States with the ATLAS and CMS Detectors

Proton-proton collisions at the Large Hadron Collider (LHC) produce an abundance of jets due to strong interactions among quarks and gluons, making multijet final states a common yet challenging signature to analyze. The ATLAS and CMS detectors are well-positioned to mine these datasets for new physics scenarios that predict high-multiplicity hadronic signatures. These channels provide key insights into potential beyond-the-Standard-Model (BSM) physics, including supersymmetry and dark matter candidates. This talk presents recent results from searches in multijet final states at ATLAS and CMS, highlighting techniques used to manage large QCD backgrounds and the application of advanced reconstruction algorithms. Findings and constraints are discussed in the context of future LHC runs and experiments.
