Quarkonium production in SM Higgs decays
Abstract
We investigate the SM Higgs decays into heavy quarkonia J/ and in both color-singlet and color-octet mechanisms. It is found that in J/ production the contribution through color-octet processes overwhelm that in color-singlet processes all the intermediate region MZ<MH0<2 Mw and the fraction ratio is comparatively large, but in production the contribution through color-octet mechanism is negligible.
