Abstract

The discovery of the Higgs boson ten years ago and successful measurement of the Higgs boson couplings to third generation fermions by LHC mark great milestones for HEP. The much weaker coupling to the second generation quarks predicted by the SM makes the measurement of the light Yukawa Higgs couplings, as the Higgs-charm ones, much more challenging. With the latest tagging algorithms capabilities, a lot of progress has been made to constrain these couplings. In this talk, the latest results of direct and indirect measurements by the CMS experiment are presented. Prospects for future improvements are also given.
