One-Loop NMHV Amplitudes involving Gluinos and Scalars in N=4 Gauge Theory
Steven J. Bidder, Warren B. Perkins, Kasper Risager
We use Supersymmetric Ward Identities and quadruple cuts to generate n-pt NMHV amplitudes involving gluinos and adjoint scalars from purely gluonic amplitudes. We present a set of…
Supersymmetric Ward Identities and NMHV Amplitudes involving Gluinos
Steven J. Bidder, David C. Dunbar, Warren B. Perkins
We show how Supersymmetric Ward identities can be used to obtain amplitudes involving gluinos or adjoint scalars from purely gluonic amplitudes. We obtain results for all one-loop…
One-Loop Gluon Scattering Amplitudes in Theories with Supersymmetries
Steven J. Bidder, N. E. J. Bjerrum-Bohr, David C. Dunbar +1
Generalised unitarity techniques are used to calculate the coefficients of box and triangle integral functions of one-loop gluon scattering amplitudes in gauge theories with $N < 4…
Twistor Space Structure of the Box Coefficients of N=1 One-loop Amplitudes
Steven J. Bidder, N. E. J. Bjerrum-Bohr, David C. Dunbar +1
We examine the coefficients of the box functions in N=1 supersymmetric one-loop amplitudes. We present the box coefficients for all six point N=1 amplitudes and certain all exa…
