Searches for New Physics at High Object Masses with CMS

Abstract

Searches at high object masses probe both resonant production of new particles and nonresonant distortions of Standard Model spectra. This contribution follows the material presented in the Moriond Electroweak 2026 talk and summarizes recent CMS results in this regime: the Run~2 combination of heavy vector boson searches, the Run~3 search for $W^\prime \to \ell \nu$, the Run~2 dijet angular analysis, and searches for pair-produced dijet resonances in inclusive and $b$-tagged final states. No significant deviation from the SM expectation is observed, and the new results extend the sensitivity of CMS to multi-TeV scales in several benchmark scenarios.
