Measurement of the Higgs boson production and decay rates from a combination of ATLAS and CMS data — •Andrew Gilbert, Günter Quast, and Roger Wolf — Karlsruher Institut für Technologie, Karlsruhe

The discovery of the Higgs boson by the ATLAS and CMS Collaborations was a major triumph of the first run of the Large Hadron Collider. The focus now switches to measuring the properties of this new particle as precisely as possible to both test the predictions of the standard model and search for deviations which would be an indication of new physics.

In this talk measurements of the Higgs boson production and decay rates from a combination of ATLAS and CMS data are presented. The combination includes an analysis of six decay modes: H→ZZ, WW, γγ, bb, ττ and µµ, and production via gluon fusion, vector-boson fusion and in association with a W or Z boson or a tt pair. Results are presented in models based on either signal strength or coupling modifier parameterisations, and the combination procedure itself is discussed.
