Search for high-mass Zγ resonances in e+e−γ and μ + μ −γ final states in proton-proton collisions at √s=8 and 13 TeV
This paper describes the search for a high-mass narrow-width scalar particle decaying into a Z boson and a photon. The analysis is performed using proton-proton collision data recorded with the CMS detector at the LHC at center-of-mass energies of 8 and 13 TeV, corresponding to integrated luminos...

| description | This paper describes the search for a high-mass narrow-width scalar particle
decaying into a Z boson and a photon. The analysis is performed using proton-proton
collision data recorded with the CMS detector at the LHC at center-of-mass energies of
8 and 13 TeV, corresponding to integrated luminosities of 19.7 and 2.7 fb−1
, respectively.
The Z bosons are reconstructed from opposite-sign electron or muon pairs. No statistically
significant deviation from the standard model predictions has been found in the 200–
2000 GeV mass range. Upper limits at 95% confidence level have been derived on the
product of the scalar particle production cross section and the branching fraction of the
Z decaying into electrons or muons, which range from 280 to 20 fb for resonance masses
between 200 and 2000 GeV. |
