Multigluonic scattering amplitudes of heavy quarks
Abstract
We consider heavy quark and antiquark off-shell spinorial currents with emission of an arbitrary number of gluons of positive helicity. From this results we calculate the corresponding on-shell scattering amplitude and the quark-antiquark vector current. Then, we show that in the heavy top quark effective theory the holomorfic component of the Higgs q q + n-gluon amplitude vanish for helicity conserving configurations.
