As the most recently-discovered particle of the Standard Model (SM), the Higgs boson plays a key role in the quest to deepen our understanding of fundamental physics. Measurements of its production cross-sections probe for disagreement with the SM that might hint at signs of new physics. I will present recent measurements of gluon fusion (ggF) and vector boson fusion (VBF) Higgs production in the H->WW*->evuv decay channel, using data from the ATLAS detector at CERN’s Large Hadron Collider (LHC). These measurements are challenging due to the high-background environment, where on average fewer than one in one billion proton-proton collisions produces Higgs bosons. I will discuss novel analysis techniques and improvements that allow the first observation of the H->WW* process in the VBF channel and precise measurements of Higgs boson cross-sections in important kinematic regions. Over the next years, the planned upgrade and corresponding increase in luminosity at the LHC will provide us with an even larger dataset. I will highlight some of the work being done to prepare the ATLAS detector for these challenging but productive conditions, which will enable further precision tests of the SM.
