Computation of Feynman loop integrals

چکیده
We address multivariate integration and extrapolation techniques for the computation of Feynman loop integrals. Loop integrals are required for perturbation calculations in high energy physics, as they contribute corrections to the scattering amplitude and the cross section for the collision of elementary particles. We use iterated integration to calculate the multivariate integrals. The combined integration and extrapolation methods aim for an automatic calculation, where little or no analytic manipulation is required before the numeric approximation.

Transformation, Reduction and Extrapolation Techniques for Feynman Loop Integrals
We address the computation of Feynman loop integrals, which are required for perturbation calculations in high energy physics, as they contribute corrections to the scattering amplitude for the collision of elementary particles. Results in this field can be used in the verification of theoretical models, compared with data measured at colliders. We made a numerical computation feasible for vari...
متن کاملReduction method for dimensionally regulated one-loop N-point Feynman integrals
We present a systematic method for reducing an arbitrary one−loop N(≥ 5)−point massless Feynman integral with generic 4−dimensional momenta to a set comprised of eight fundamental scalar integrals: six box integrals in D = 6, a triangle integral in D = 4, and a general two−point integral in D = 4 + 2ε space time dimensions. All IR divergences present in the original integral are contained in th...
متن کاملParallel computation of Feynman loop integrals
The need for large numbers of compute-intensive integrals, arising in quantum field theory perturbation calculations, justifies the parallelization of loop integrals. In earlier work, we devised effective multivariate methods by iterated (repeated) adaptive numerical integration and extrapolation, applicable for some problem classes where standard multivariate integration techniques fail throug...

All three-loop on-shell QCD Feynman integrals with two masses can be reduced to 27 master integrals. Here we calculate these master integrals, expanded in ε, both exactly in the mass ratio and as series in limiting cases.
