dc.description.abstract	The thesis presents the measurement of Higgs boson production in association with a leptonically decaying Z boson and cross-section is measured in terms of signal strength modifier and signal significance. The events where the Higgs decays to a pair of W bosons are considered. These measurements have been performed using the LHC data from pp collisions, collected by CMS during Run-II (2016-2018) at and#8730;s = 13 TeV, corresponding to an integrated luminosity of 137 fb-1. The multivariate Boosted Decision Tree (BDT) discriminant is used to differentiate the signal and background in the signal region. The combined measurement is also presented which includes other vector boson associated production modes of the Higgs boson. newline
