The proper decay time, t, distributions in the $\mathrm{Z}$ (upper) and Higgs (lower) boson searches. Distributions in simulated events are normalized to the number of selected events in data. The distributions suggest that the $\mathrm{J}/\psi$ candidates reconstructed in data, just as signal events, are produced promptly at the $\mathrm{p}\mathrm{p}$ interaction point, and not from displaced heavy-hadron decays
