文摘We presented the calculation of the decay width for the massive top quark accompanied by a emission of two hard gluons.It is shown that the top quark decay channel with two-gluon bremsstrahlung increases its total width by 2%to 7%,so that this contribution is non-negligible and should be included in considering top decay.
