Description
Novel trigger strategies, combined with the large proton-proton collision datasets collected by the CMS experiment, have extended its sensitivity to rare flavor decay processes. Leveraging CMS’s ability to efficiently trigger on and reconstruct low-momentum muons, the experiment offers complementary sensitivity to rare meson decays.
This contribution presents recent results on η meson decays from the CMS experiment. We report the first observation of the rare double Dalitz decay η → μ⁺μ⁻μ⁺μ⁻, achieved through the use of dedicated low-pT dimuon triggers. We also discuss the innovative trigger developments introduced for Run 3 and outline the future prospects for probing rare η and η' decays at CMS.
