Reproducing the CMS experiments' logo with J/ψ decays to four muons

The J/ψ meson, a pivotal particle in quantum chromodynamics (QCD), decays into four muons (J/ψ → μ+μ−μ+μ−) as observed by the CMS detector at CERN, a digital high energy physics camera. The event display remarkably resembles the CMS logo, showing the four muons as lines. This rare decay, captured in our image, provides vital insights into QCD, quantum electrodynamics (QED), and tests lepton flavor universality. Such decays are instrumental in probing the fundamental interactions and exploring physics beyond the Standard Model. Our work paves the way for a deeper understanding of particle interactions in the universe.
