Antenna Factorization of Gauge-Theory Amplitudes
David A. Kosower
I derive a single factorization formula which summarizes all soft and collinear divergences of a tree-level gauge theory amplitude. The singular factor squared is in a certain sens…
One-Loop Amplitudes for e^+ e^- to Four Partons
Z. Bern, L. Dixon, D. A. Kosower
We present the first explicit formulae for the complete set of one-loop helicity amplitudes necessary for computing next-to-leading order corrections for e^+ e^- annihilation into…
Extracting Parton Densities from Collider Data
David A. Kosower
Collider data can play an important role in determining the parton distribution functions of the nucleon. I present a formalism which makes it possible to use next-to-leading order…
Advanced Techniques for Multiparton Loop Calculations: A Minireview
Zvi Bern, Lance Dixon, David C. Dunbar +1
We present an overview of techniques developed in recent years for the efficient calculation of one-loop multiparton amplitudes, in particular those relying on unitarity and collin…
Parton Densities from Collider Data
David A. Kosower
Collider data can play an important role in determining the parton distribution functions of the nucleon. I outline a formalism which makes it possible to use next-to-leading order…
Evolution of Parton Distributions
David A. Kosower
I present a highly efficient method for evolving parton distributions in perturbative QCD. The method allows evolving the parton distribution functions according to any of the comm…
