Supersymmetric Ward Identities and NMHV Amplitudes involving Gluinos
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 six-point NMHV amplitudes in \NeqFour Super
Yang-Mills theory which involve two gluinos or two scalar particles. More
general cases are also discussed.Comment: 32 pages, minor typos fixed; one reference adde
One-Loop NMHV Amplitudes involving Gluinos and Scalars in N=4 Gauge Theory
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 factors that can be used to generate one-loop
NMHV amplitudes involving gluinos or adjoint scalars in N=4 Super Yang-Mills
from the corresponding purely gluonic amplitude.Comment: 16 pages, JHEP versio
Twistor Space Structure of the Box Coefficients of N=1 One-loop Amplitudes
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 example coefficients. We find for ``next-to
MHV'' amplitudes that these box coefficients have coplanar support in twistor
space.Comment: 14 pages, minor typos correcte

One-loop gluon scattering amplitudes in theories with supersymmetries
AbstractGeneralised 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 supersymmetries. We show that the box coefficients in N=1 and N=0 theories inherit the same coplanar and collinear constraints as the corresponding N=4 coefficients. We use triple cuts to determine the coefficients of the triangle integral functions and present, as an example, the full expression for the one-loop amplitude AN=1(1â,2â,3â,4+,âŠ,n+)
