Title: Light quark Yukawa couplings from Higgs kinematics

We show that the normalized Higgs production p T and y h distributions are sensitive probes of Higgs couplings to light quarks. For up and/or down quark Yukawa couplings comparable to the SM b quark Yukawa the $$\bar{u}u$$ or $$\bar{d}d$$ fusion production of the Higgs could lead to appreciable softer p T distribution than in the SM. The rapidity distribution, on the other hand, becomes more forward. Here, we find that, owing partially to a downward fluctuation, one can derive competitive bounds on the two couplings using ATLAS measurements of normalized p T distribution at 8TeV. With 300 fb -1 at 13TeV LHC one could establish flavor non-universality of the Yukawa couplings in the down sector.
