One-Loop Gluonic Amplitudes from Single Unitarity Cuts
E. W. Nigel Glover, Ciaran Williams
We show that one-loop amplitudes in massless gauge theories can be determined from single cuts. By cutting a single propagator and putting it on-shell, the integrand of an n-point…

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…
