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…
Non-MHV Tree Amplitudes in Gauge Theory
George Georgiou, E. W. N. Glover, Valentin V. Khoze
We show how all non-MHV tree-level amplitudes in 0 =< N =< 4 gauge theories can be obtained directly from the known MHV amplitudes using the scalar graph approach of Cachazo, Svrce…
Numerical Evaluation of One-Loop Diagrams Near Exceptional Momentum Configurations
W. Giele, E. W. N. Glover, G. Zanderighi
One problem which plagues the numerical evaluation of one-loop Feynman diagrams using recursive integration by part relations is a numerical instability near exceptional momentum c…
Two-loop splitting functions in QCD
S. D. Badger, E. W. N. Glover
We present the universal two-loop splitting functions that describe the limits of two-loop -point amplitudes of massless particles when two of the momenta are collinear. To deri…
Infrared Structure of jets at NNLO
A. Gehrmann-De Ridder, T. Gehrmann, E. W. N. Glover
The production of two jets is the simplest exclusive quantum chromodynamics process in electron-positron annihilation. Using this process, we examine the structure of next-to-next-…
A Calculational Formalism for One-Loop Integrals
W. T. Giele, E. W. N. Glover
We construct a specific formalism for calculating the one-loop virtual corrections for standard model processes with an arbitrary number of external legs. The procedure explicitly…
