A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals
Shinji Motoki, Hiroshi Daisaka, Naohito Nakasato +5
Higher order corrections in perturbative quantum field theory are required for precise theoretical analysis to investigate new physics beyond the Standard Model. This indicates tha…
Analytic and numerical approaches for depictive 3-loop integrals using sector decomposition
Elise de Doncker, Tadashi Ishikawa, Kiyoshi Kato +1
Four 3-loop two-point functions are studied analytically and numerically using a simplified sector decomposition method. The coefficients of the ultraviolet divergent part are dete…
The International Linear Collider: Report to Snowmass 2021
Alexander Aryshev, Ties Behnke, Mikael Berggren +508
The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our…
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…
Extrapolation Algorithms for Infrared Divergent Integrals
Elise de Doncker, Junpei Fujimoto, Nobuyuki Hamaguchi +5
This paper describes applications of extrapolation for the computation of coefficients in an expansion of infrared divergent integrals. An extrapolation procedure is performed with…
