Twistor-Inspired Construction of Electroweak Vector Boson Currents
Zvi Bern, Darren Forde, David A. Kosower +1
We present an extension of the twistor-motivated MHV vertices and accompanying rules presented by Cachazo, Svrvcek and Witten to the construction of vector-boson currents coupling…
Two-loop helicity amplitudes for fermion-fermion scattering
A. De Freitas, Z. Bern
We discuss the calculation of two-loop helicity amplitudes for quark-quark scattering in QCD and four-gluino scattering in N=1 supersymmetric Yang-Mills theory. We study the depend…
Two-Loop Helicity Amplitudes for Quark-Quark Scattering in QCD and Gluino-Gluino Scattering in Supersymmetric Yang-Mills Theory
Abilio De Freitas, Zvi Bern
We present the two-loop QCD helicity amplitudes for quark-quark and quark-antiquark scattering. These amplitudes are relevant for next-to-next-to-leading order corrections to (pola…
Two-loop Splitting Amplitudes
Z. Bern, L. J. Dixon, D. A. Kosower
Splitting amplitudes govern the behavior of scattering amplitudes at the momenta of external legs become collinear. In this talk we outline the calculation of two-loop splitting am…
Two-Loop g -> gg Splitting Amplitudes in QCD
Zvi Bern, Lance J. Dixon, David A. Kosower
Splitting amplitudes are universal functions governing the collinear behavior of scattering amplitudes for massless particles. We compute the two-loop g -> gg splitting amplitudes…
