Abstract:We study the decay of the SM Higgs boson to massive charm quark pair at the next-to-next-toleading order QCD and next-to-leading order electroweak. At the second order of QCD coupling, we consider the exact calculation of flavour-singlet contributions where the Higgs boson couples to the internal top and bottom quark. Some helpful information on the running mass effects related to Yukawa coupling may be obtained by analyzing this process. High precision production for h → cc within SM makes it possible to sear… Show more
