Observation of the Z →ψ + - decay in pp collisions at s =13 TeV

Observation of the Z →ψ + - decay in pp collisions at s =13 TeV

This Letter presents the observation of the rare Z boson decay Z → ψlþl−. Here, ψ represents contributions from direct J=ψ and ψð2SÞ → J=ψX, lþl− is a pair of electrons or muons, and the J=ψ meson is detected via its decay to μþμ−. The sample of proton-proton collision data, collected by the CMS...
