Extracting the Gluon Fusion Component of the Associated ZH Production with the CMS Experiment — •Svenja Diekmann, Niclas Eich, and Martin Erdmann — III. Physikalisches Institut A, RWTH Aachen University
The gluon fusion production mechanism of the associated ZH production (gg → ZH) is a yet unmeasured Standard Model process sensitive to various new physics scenarios. The considered final state of two leptons and two b-jets is not only populated by large backgrounds arising from other processes, but also by the dominant quark initiated ZH production (qq → ZH). In order to separate these two production mechanisms, the total ZH production can be utilised in combination with the WH production to extract the gluon fusion component by analysing the ratio of their cross sections. The strategy of this analysis to extract the gluon fusion component of the ZH production is demonstrated using the data-taking period 2017 of the CMS experiment.
