Latest results on Standard Model Higgs boson in the WW* decay channel using the ATLAS detector

Higgs boson production cross-sections via the gluon-gluon fusion and vector-boson fusion modes are measured in the H→WW*→eνμν decay channel in the ATLAS experiment at the LHC. The H→WW* decay channel has the second largest branching fraction and allows to measure Higgs boson production cross-section with good precision. The analysis based on the proton-proton collision data produced at the LHC at a centre-of-mass energy of 13 TeV and recorded by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of 36.1 fb$^{-1}$ will be presented in this talk. Moreover, future prospectives on the WW channel using the full available data will be discussed.
