Higgs boson's discovery in 2012 by CMS and ATLAS was a great achievement of the 20'th century, Prof. Peter Higgs and Prof. Francois Englert were awarded the Nobel Prize in 2014. After its discovery, the next milestone of particle physics is to measure its properties precisely. To measure its properties, H -> WW decay channel is considered, where W is again decaying into an electron or muon with the presence of ν (neutrinos) in the final state (H ->W+W- -> l+l-νν ). Measurement of differential and inclusive cross-section with respect to pTH(transverse momentum of Higgs) and Njet(no. of jets) has been performed using full run 2 data of total integrated luminosity of 137.0 fb-1 collected by the CMS detector at the center of mass energy √s = 13 TeV. Final results are published in JHEP with the measured value of inclusive cross-section is 86.5 ± 9.5 fb, which is consistent with SM theoretical predictions and within the acceptance of experimental uncertainties.

Constraints of AC (Anomalous Coupling) of Higgs can be probed using EFT (Effective field theory) approach to search BSM physics. Following analysis is performed in the associated Higgs production separately for WH -> 3l and ZH -> 4l final state with the use of full Run 2 data. No Beyond Standard Model signature is observed.
