Multi gluon collinear limits from MHV amplitudes
P. Marquard, T. G. Birthwright
We consider the multi-collinear limit of multi-gluon QCD amplitudes at tree level. We use the MHV rules for constructing colour ordered tree amplitudes and the general collinear fa…
Collinear Limits in QCD from MHV Rules
T. G. Birthwright, E. W. N. Glover, V. V. Khoze +1
We consider multi-parton collinear limits of QCD amplitudes at tree level. Using the MHV formalism we specify the underlying analytic structure of the resulting multi-collinear spl…
Multi-Gluon Collinear Limits from MHV diagrams
T. G. Birthwright, E. W. N. Glover, V. V. Khoze +1
We consider the multi-collinear limit of multi-gluon QCD amplitudes at tree level. We use the MHV rules for constructing colour ordered tree amplitudes and the general collinear fa…
Master Integrals For Massless Two-Loop Vertex Diagrams With Three Offshell Legs
T. G. Birthwright, E. W. N. Glover, P. Marquard
We compute the master integrals for massless two-loop vertex graphs with three off-shell legs. These master integrals are relevant for the QCD corrections to H to V*V* (where V = W…
