General subtraction method for numerical calculation of one-loop QCD matrix elements
We present a subtraction scheme for eliminating the ultraviolet, soft, and collinear divergences in the numerical calculation of an arbitrary one-loop QCD amplitude with an arbitrary number of external legs. The subtractions consist of local counter terms in the space of the four-dimensional loop momentum. The ultraviolet subtraction terms reproduce MS renormalization. The key point in the meth...
متن کاملRecursive Approach to One-loop QCD Matrix Elements
Recently, a “weak-weak” duality, between N = 4 super Yang-Mills and a topological string theory propagating in twistor space, has been proposed [1] implying an identical perturbative S-matrix for the two theories. The existence of a duality between the two theories implies a surprising structure within the S-matrix of gauge theory. This has inspired considerable progress in computing scattering...
متن کاملNumerical evaluation of one-loop QCD amplitudes
We present the implementation of the numerical generalized unitarity algorithm in the public code NJET. As phenomenological applications we discuss three and four jet production at the LHC to next-to-leading order accuracy in massless QCD.
متن کاملMatching between matrix elements and parton showers using a Leading-Log subtraction method in NLO-QCD
A new method to construct event-generators based on next-to-leading order QCDmatrixelements and leading-logarithmic parton showers is proposed. Matrix elements of loop diagrams as well as those of a tree level can be generated using an automatic system. A soft/collinear singularity is treated using a leading-log subtraction method. Higher order re-summation of the soft/collinear correction by t...
متن کاملRecursive Calculation of One-Loop QCD Integral Coefficients
We present a new procedure using on-shell recursion to determine coefficients of integral functions appearing in one-loop scattering amplitudes of gauge theories, including QCD. With this procedure, coefficients of integrals, including bubbles and triangles, can be determined without resorting to integration. We give criteria for avoiding spurious singularities and boundary terms that would inv...
