Mixed precision solvers with half-precision floating point numbers for Lattice QCD on A64FX processor
Issaku Kanamori, Hideo Matsufuru, Tatsumi Aoyama +4
We investigate the use of half-precision floating-point numbers (FP16) in mixed-precision linear solvers for lattice QCD simulations. Since the emergence of GPUs for general-purpos…

The anomalous magnetic moment of the muon in the Standard Model: an update
R. Aliberti, T. Aoyama, E. Balzani +232
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…

Verification of the tenth-Order QED contribution to the anomalous magnetic moment of the electron from diagrams without fermion loops
Tatsumi Aoyama, Masashi Hayakawa, Akira Hirayama +1
A discrepancy of approximately 5 exists between the two known results for the tenth-order QED contribution to the anomalous magnetic moment of the electron, calculated from Fey…
