| Abstract: | In top quark decay a neutral Higgs boson may be emitted in bremsstrahlung from the top quark or from the W-boson. We evaluate the branching fraction for this hitherto overlooked t→H0bW+ decay mode, where the W+ can be virtual or real. It has the standard model values of 0.02%, 0.2%, 0.8% for mt=50, 100, 200 GeVand mH=10 GeV. |
