ATLAS and CMS Experiment Shed Light on Higgs Properties

Results of the analyses

Results of the analyses by individual experiments (coloured) and both experiments together (black), showing the improvement in precision resulting from the combination of results.

Three years after the announcement of the discovery of a new particle — the so-called Higgs boson — the ATLAS and CMS Collaborations presented for the first time combined measurements of many of its properties at the third annual Large Hadron Collider Physics Conference. By combining their analyses of the data collected in 2011 and 2012, ATLAS and CMS drew the sharpest picture yet of this novel boson. The new results provide in particular the best precision on its production and decay and on how it interacts with other particles.  All of the measured properties are in agreement with the predictions of the Standard Model and will become the reference for new analyses in the coming months, enabling the search for new physics phenomena. This follows the best measurement of the mass of the Higgs boson, published in May 2015 after a combined analysis by the two collaborations.
