The resonance considered is a light boson with a mass below $4~\\text{GeV}$ from a possible extended scalar sector, or a charmonium state. Multivariate discriminants are used for the event selection and for evaluating the mass of the light resonance. No excess of events above the expected background is found. Observed (expected) 95% confidence-level upper limits are set on the Higgs boson production cross section times branching fraction to a $Z~\\text{boson}$ and the signal resonance, with values in the range $17~\\text{pb}$ to $340~\\text{pb}$ ($16^{+6}_{-5}~\\text{pb}$ to $320^{+130}_{-90}~\\text{pb}$) for the different light spin-0 boson mass and branching fraction hypotheses, and with values of $110~\\text{pb}$ and $100~\\text{pb}$ ($100^{+40}_{-30}~\\text{pb}$ and $100^{+40}_{-30}~\\text{pb}$) for the $\\eta_c$ and $J/\\psi$ hypotheses, respectively.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.93626.v1/t1","@type":"Dataset","description":"Observed number of data events and expected number of background events in the signal region.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.93626.v1/t2","@type":"Dataset","description":"Efficiencies of the MLP selection, complete selection and total expected signal yields for each signal sample, assuming B$(H\\to Z(Q/a))=100\\%$ and...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.93626.v1/t3","@type":"Dataset","description":"Expected and observed 95% CL upper limits on $\\sigma(pp\\to H)B(H\\to Za)/$pb.
