Automatic calculation of one-loop amplitudes
نویسندگان
چکیده
An algorithm to automatically compute any one-loop amplitude for all momentum, color, and helicity configurations of the external particles is presented. It has been implemented using the tools HELAC for the evaluation of tree-level off-shell currents, CutTools for OPP-reduction and OneLOop for the evaluation of one-loop scalar integrals. It proves to be able to deal with at least all sub-processes included in the 2007 Les Houches wish list for LHC involving 3 or 4 particles in the final state.

Light-by-light scattering amplitudes from generalized unitarity in massive QED
We calculate all the four-photon helicity amplitudes at the one-loop level in a massive theory using multiple-cut methods. The amplitudes are derived in scalar QED, QED and QED theories. We will see the origin of rational terms. We extend the calculation to the simplest six-photon helicity amplitude where all photons have the same helicity.

متن کاملAmplitudes in Pure Yang-Mills and MHV Diagrams
We show how to calculate the one-loop scattering amplitude with all gluons of negative helicity in non-supersymmetric Yang-Mills theory using MHV diagrams. We argue that the amplitude with all positive helicity gluons arises from a Jacobian which occurs when one performs a Bäcklund-type holomorphic change of variables in the lightcone Yang-Mills Lagrangian. This also results in contributions to...
متن کاملA Fully Numerical Approach to One-Loop Amplitudes
We suggest a new approach for the automatic and fully numerical evaluation of oneloop scattering amplitudes in perturbative quantum field theory. We use suitably formulated dispersion relations to perform the calculation as a convolution of treelevel amplitudes. This allows to take advantage of the iterative numerical algorithms for the evaluation of leading order matrix elements. Preprint subm...
متن کاملBPS Amplitudes, Helicity Supertraces and Membranes in M-Theory
We study BPS dominated loop amplitudes in M-theory on T 2. For this purpose we generalize the concept of helicity supertraces to nine spacetime dimensions. These traces distinguish between various massive supermultiplets and appear as coefficients in their one-loop contributions to n-graviton scattering amplitudes. This can be used to show that only ultrashort BPS multiplets contribute to the R...
متن کاملOne - loop corrections to the D 3 brane action
We calculate one-loop corrections to the effective Lagrangian for the D3 brane. We perform the gauge-fixing of the κ-symmetric Born-Infeld D3 brane action in the flat background using Killing gauge. The linearized supersymmetry of the gaugefixed action coincides with that of the N = 4 Yang-Mills theory. We use the helicity amplitude and unitarity technique to calculate the one-loop amplitudes a...
