Recursion Relations for Gauge Theory Amplitudes with Massive Vector Bosons and Fermions
S. D. Badger, E. W. N. Glover, Valentin V. Khoze
We apply the on-shell tree-level recursion relations of Britto, Cachazo, Feng and Witten to a variety of processes involving internal and external massive particles with spin. We s…
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…
Recursion Relations for Gauge Theory Amplitudes with Massive Particles
S. D. Badger, E. W. N. Glover, V. V. Khoze +1
We derive general tree-level recursion relations for amplitudes which include massive propagating particles. As an illustration, we apply these recursion relations to scattering am…
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…
