Status reports from the GRACE Group
Y. Yasui, T. Ueda, E. de Doncker +5
We discuss a new approach for the numerical evaluation of loop integrals. The fully numerical calculations of an infrared one-loop vertex and a box diagram are demonstrated. To per…
Precise Numerical Evaluation of the Scalar One-Loop Integrals with the Infrared Divergence
F. Yuasa, E. de Doncker, J. Fujimoto +3
We present a new approach for obtaining very precise integration results for infrared vertex and box diagrams, where the integration is carried out directly without performing any…
Recent Developments in Parallelization of the Multidimensional Integration Package DICE
F. Yuasa, K. Tobimatsu, S. Kawabata
DICE is a general purpose multidimensional numerical integration package. There can be two ways in the parallelization of DICE, "distributing random numbers into workers" and "dist…
Loop integration results using numerical extrapolation for a non-scalar integral
E. de Doncker, Y. Shimizu, J. Fujimoto +4
Loop integration results have been obtained using numerical integration and extrapolation. An extrapolation to the limit is performed with respect to a parameter in the integrand w…
Hybrid Parallel Computation of Integration in GRACE
Fukuko Yuasa, Tadashi Ishikawa, Setsuya Kawabata +4
With an integrated software package {\tt GRACE}, it is possible to generate Feynman diagrams, calculate the total cross section and generate physics events automatically. We outlin…
