Measurements of Higgs boson production using decays to two c-quarks with the ATLAS detector

Content

Testing the couplings of the Higgs boson to quarks is important to understand the origin of quark masses. The next most promising candidate is the decay to a pair of charm quark and antiquark.

The presentation will focus on the analysis of the associated production of the Higgs boson with a W or Z boson performed by the ATLAS Collaboration using data collected between 2015 and 2018, and will describe the analysis strategy employed to search for the H→cc signal. As a result, the best limit set on Higgs to charm quark Yukawa coupling modifier (κC) to date will be shown.
