A development of an accelerator board dedicated for multi-precision arithmetic operations and its application to Feynman loop integrals II
H Daisaka, N Nakasato, T Ishikawa +2
Evaluation of a wide variety of Feynman diagrams with multi-loop integrals and physical parameters and its comparison with high energy experiments are expected to investigate new p…
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…
Low temperature limit of lattice QCD
K. Nagata, A. Nakamura, S. Motoki
We study the low temperature limit of lattice QCD by using a reduction formula for a fermion determinant. The reduction formula, which is useful in finite density lattice QCD simul…
Towards extremely dense matter on the lattice
Keitaro Nagata, Shinji Motoki, Yoshiyuki Nakagawa +2
QCD is expected to have a rich phase structure. It is empirically known to be difficult to access low temperature and nonzero chemical potential regions in lattice QCD simulati…
Development of Lattice QCD Tool Kit on Cell Broadband Engine Processor
Shinji Motok, i Yoshiyuki Nakagawa, Keitaro Nagata +3
We report an implementation of a code for SU(3) matrix multiplication on Cell/B.E., which is a part of our project, Lattice Tool Kit on Cell/B.E.. On QS20, the speed of the matrix…
Lattice QCD and High Baryon Density State
Atsushi Nakamura, Keitaro Nagata, Shinji Motoki +2
We report our recent studies on the finite density QCD obtained from lattice QCD simulation with clover-improved Wilson fermions of two flavor and RG-improved gauge action. We appr…
