Subleading effects in soft-gluon emission at one-loop in massless QCD

Subleading effects in soft-gluon emission at one-loop in massless QCD

Abstract We elucidate the structure of the next-to-leading-power soft-gluon expansion of arbitrary one-loop massless-QCD amplitudes. The expansion is given in terms of universal colour-, spin- and flavour-dependent operators acting on process-dependent gauge-invariant amplitudes. The result is prove...
