| contents | The decay $H \to ZZ \to 4\ell$, with $\ell = e,μ$, can be used to test quantum interference in analogy to the famous double-slit experiment. The observations corresponding to `covering a slit' can be extracted from data in the $eeμμ$ channel, while the observations when both `slits' are open, which include the interference, are measured in the $4e/4μ$ channels. In this way, this process offers a unique opportunity to investigate identical-particle effects at high energies, and provide the first evidence of identical-particle behaviour for muons. Sensitivity at the $4σ$ level could be achieved at the high-luminosity upgrade of the Large Hadron Collider. |
