Measurement of pp→ WH→ WWW with the ATLAS Experiment — •Moritz Hesping, Volker Büscher, Ralf Gugel, and Christian Schmitt — Johannes Gutenberg Universität Mainz

The measurement of the couplings of the Higgs boson is of great scientific interest, since it has the potential of testing possible extensions to the Standard Model. The decay of a Higgs boson into a pair of W bosons after production in association with a W boson is especially useful, since in this process the Higgs boson exclusively couples to W bosons.

In this talk, the analysis of the pp→ WH→ WWW using the full run 2 dataset of the ATLAS experiment will be presented, focusing on the three lepton Z-depleted channel. First preliminary results for this analysis will be shown. Finally, the extension of the analysis to the Simplified Template Cross Sections (STXS) scheme will be discussed. In the STXS scheme, the measurement is performed as a function of the momentum of the associated W boson, which gives improved sensitivity to possible contributions from physics beyond the standard model.
