The most challenging measurement in Higgs phsyiscs today is its coupling to Charm quarks. This measurement is essential to prove that the coupling of the Higgs Boson to elementary particles is proportiona to their mass. To probe the Higgs we use its associate production with a vecor Boson, Z or W (pp->VH->Vcc). The final states will be a pair of charm quarks with either 2 leptons, one lepton or zero lepton. We are now developing the zero leptons analysis. The work is done in collaboration with teh experimental HEP group in TAU. The measurement is performed with the ATLAS detector at the Large hadron Collider , CERN.
