Search for the Higgs boson decay to a pair of charm quarks at CMS — •Andrey Pozdnyakov¹, Xavier Coubez^1,2, Luca Mastrolorenzo¹, Spandan Mondal¹, Andrzej Novak¹, and Alexander Schmidt¹ — ¹RWTH, Aachen, Germany — ²Brown University, Providence, USA

Coupling of the Higgs boson to top and bottom quarks has been firmly established. It is now time to determine its coupling to second generation fermions. In this talk the coupling of the Higgs boson to charm quarks is probed in a direct search for H -> cc decay, where H boson is produced in association with a W or Z boson. Key feature of the analysis is the ability to tag jets from Higgs boson decay as charm-quark jets and distinguish them from gluon or light-quark initiated jets. This is done using sophisticated jet tagging algorithms employing Deep Neural Network techniques.
