| 英文摘要 | 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 13tev, 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 signi fi cant deviation from the standard model predictions has been found in the 200-2000 gev mass range. upper limits at 95% con fi dence 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. |
