A direct search for the standard model Higgs boson decaying to a pair of charm quarks is presented. Associated production of the Higgs and Z bosons, in the decay mode ZHââ^{+}â^{-}cc[over ¯] is studied. A data set with an integrated luminosity of 36.1 fb^{-1} of pp collisions at sqrt[s]=13TeV recorded by the ATLAS experiment at the LHC is used. The Hâcc[over ¯] signature is identified using charm-tagging algorithms. The observed (expected) upper limit on σ(ppâZH)×B(Hâcc[over ¯]) is 2.7 (3.9_{-1.1}^{+2.1}) pb at the 95% confidence level for a Higgs boson mass of 125 GeV, while the standard model value is 26 fb.
