A search for resonance in the final state of llg is presented using 2.6 fb-1 (2015 run of LHC) and
12.9 fb-1 (2016 run of LHC) of data at sqrt(s) = 13 TeV with the CMS detector. Here l refers to e, m. The resonance particle (X) is
assumed to decay to Zg giving a final state of llg. Combined results from 8TeV (Run I) and 13 TeV (Run II) are also presented.
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.
