Three-Jet Production of Hadrons in Higgs-Boson Decay Н → qq¯g.

Within the framework of the standard model (SM), the decay of the Higgs boson into a quark-antiquark pair with gluon emission is studied. An analytical expression is obtained for the decay width, and a dependence of the decay width on the quark and antiquark energies is studied. By integrating over the quark and antiquark energies, the full width of the Higgs boson decay Н → q q ¯ g is determined. [ABSTRACT FROM AUTHOR]
