Probing Higgs-charm coupling, for current and future LHC

We introduce four different types of data­driven analyses that constrain the size of the Higgs­charm Yukawa coupling: (i) recasting the vector­boson associated, Vh, analyses that search for bottom­pair final state; (ii) the direct measurement of the total width; (iii) the search to h­> J/\psi\gamma; (iv) a global fit to the Higgs signal strengths. A comparison with t\bar{t}h data allows us to show that the Higgs does not couple to quarks in a universal way. Finally, we demonstrate how the experimental collaborations can further improve our direct bound (i) using charm­tagging.
