One-Loop Self-Dual and N=4 Super Yang-Mills
Z. Bern, L. Dixon, D. C. Dunbar +1
We conjecture a simple relationship between the one-loop maximally helicity violating gluon amplitudes of ordinary QCD (all helicities identical) and those of N=4 supersymmetric Ya…
One-Loop Amplitudes for e^+ e^- to q-bar q Q-bar Q
Z. Bern, L. Dixon, D. A. Kosower +1
We present the one-loop helicity amplitudes for processes involving a vector boson V (V=W,Z, or gamma^*) and four massless quarks, 0 to V q-bar q Q-bar Q, where V couples to a mass…
Light Gluinos and Jet Production in Collisions
Zvi Bern, Aaron K. Grant, Andrew G. Morgan
The impact of a light, long lived gluino on jet production cross sections in collisions is estimated. The effect is found to be relatively modest, particularly when glui…
Unitarity-based Techniques for One-Loop Calculations in QCD
Z. Bern, L. Dixon, D. A. Kosower
We discuss new techniques developed in recent years for performing one-loop calculations in QCD, and present an example of results from the process 0 -> V q q-bar g g. Talk present…
Progress in One-Loop QCD Computations
Z. Bern, L. Dixon, D. A. Kosower
We review progress in calculating one-loop scattering amplitudes required for next-to-leading-order corrections to QCD processes. The underlying technical developments include the…
