CMS presented a series of new results at the annual LHCP conference, which took place in Belgrade, Serbia. 

The LHCP conference provides a detailed review of the latest experimental and theoretical results related to the physics of the Large Hadron Collider.

From research within the standard model to searches for new particles and phenomena, CMS was involved across the board throughout the conference.

The CMS Collaboration presented new processes: the first evidence for the production of a top quark in association with a W boson and a Z boson, the first evidence for the Higgs boson decay to a Z boson and a photon, and the first observation of the Λ0b→J/ψ Ξ− K+ decay. These studies establish the groundwork for future measurements, with relevant implications for further investigations, as larger event samples are collected.

A new, differential study of diboson ZZ production in association with jets has been shown. Although we see an overall agreement, significant discrepancies between predicted and measured values are observed in some regions.

The wide range of searches for new physics presented at the conference included a search for dimuon resonance production in association with one or more b quark jets, a search for leptoquarks produced in lepton-quark collisions and coupling to τ leptons, a search for narrow hadronic resonances decaying to three resolved jets, a search for violation of Lorentz invariance in top-antitop production, and a search for the lepton flavour violating tau to 3 muons decay.

Looking back at an incredible week, here are the analyses that have been presented.
