Collinear limits of one-loop helicity amplitudes in QCD

Research output: Contribution to journalArticle


We point out that for QCD subprocesses involving multiple quark pairs, it is useful to investigate the collinear limits of full helicity amplitudes. We study the recently calculated one-loop {Mathematical expression} helicity amplitudes and confirm the results found by Bern, Dixon, Dunbar and Kosower for the loop splitting amplitudes.
