Progress in One - Loop Qcd Computations

چکیده
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 spinor helicity formalism, color decompositions, supersymmetry, string theory, factorization and unitarity. We provide explicit examples illustrating these techniques. To appear in Annual Reviews of Nuclear and Particle Science (1996). lResearch supported in part by the US Department of Energy under grants DEFG03-91ER40662 and DE-AC03-76SF00515, by the Alfred P.

On-Shell Unitarity Bootstrap for QCD Amplitudes∗
Seeking and measuring new physics at the imminent Large Hadron Collider (LHC) will require extensive calculations of high-multiplicity backgrounds in perturbative QCD to next-to-leading order (NLO). The Les Houches 2005 workshop defined a target list, reproduced in table 1, for theorists to attack. In addition to the processes in the table, one would also like to compute processes such as W,Z +...
متن کاملTwo-Loop N=4 Supersymmetric Amplitudes and QCD
Two-loop four-gluonN = 4 susy amplitudes are evaluated via cutting techniques as a testing ground for QCD. A conjecture for four-point amplitudes to all loop orders is described. We also present a new conjecture for the leadingcolor part of the two-loop five-gluon amplitudes. INTRODUCTION Over the years there have been a number of rather impressive Feynman diagram calculations at two and higher...
متن کاملOne-loop Gauge Theory Amplitudes with an Arbitrary Number of External Legs
We review recent progress in calculations of one-loop QCD amplitudes. By imposing the consistency requirements of unitarity and correct behavior as the momenta of two legs become collinear, we construct ansätze for one-loop amplitudes with an arbitrary number of external legs. For supersymmetric amplitudes, which can be thought of as components of QCD amplitudes, the cuts uniquely specify the a...
متن کاملExploiting Twistor Techniques for One-loop QCD Amplitudes
Recently, a “weak-weak” duality between massless gauge theory and a topological string theory propagating in twistor space has been proposed in ref. [1]. This duality implies surprising structure within the S-matrix of gauge theories. In supersymmetric theories this has been exploited to facilitate considerable progress in computing scattering amplitudes. The application of these ideas to QCD h...
متن کاملSTRING - BASED PERTURBATIVE METHODS FOR GAUGE THEORIES Zvi
Recent progress in the computation of one-loop gluon amplitudes is reviewed. These methods were originally derived from superstring theory and are significantly more efficient than conventional Feynman rules. With these methods, explicit computations can be performed beyond those achieved by traditional methods. Abstract Recent progress in the computation of one-loop gluon amplitudes is reviewe...
