Badger, Simon and Buciuni, Francesco and Peraro, Tiziano (2015) 'One-loop triple collinear splitting amplitudes in QCD.', Journal of high energy physics., 2015 (9). p. 188.
We study the factorisation properties of one-loop scattering amplitudes in the triple collinear limit and extract the universal splitting amplitudes for processes initiated by a gluon. The splitting amplitudes are derived from the analytic Higgs plus four partons amplitudes. We present compact results for primitive helicity splitting amplitudes making use of super-symmetric decompositions. The universality of the collinear factorisation is checked numerically against the full colour six parton squared matrix elements.
