$B_c$ Production in Higgs Boson Decays

High Energy Physics - Phenomenology 2016-03-23 v2

Abstract

BcB_c production rate in Higgs boson decays is evaluated in NRQCD framework. Given Higgs total decay width is about 4.20 MeV4.20~MeV and the vector BcB^*_c meson decays completely to the ground state, we find that the branching fraction of BcB_c meson production in Higgs decays is 8.50×1048.50\times10^{-4}, where both leading QED and QCD contributions are included. This process is hence detectable in the high-luminosity/energy LHC. In confronting to the quarkonia production, we find that the fraction rate of BcB_c production is more than an order of magnitude bigger than those of charmonium and bottomoium production in Higgs decays. In the calculation, various differential distributions and uncertainties of the concerned processes are analysed.
