Abstract

Lattice QCD calculations are crucial to understanding and interpreting the results from particle collider experiments such as at the upcoming LHC in CERN. The simulations are numerically very expensive and require high-capability HPC resources. Theoretical calculations can be carried out to improve the accuracy and efficiency of the simulations. These supporting, ’improvement’ calculations can be carried out using capacity HPC resources.
In this project we continue to use DEISA resources to carry out such improvement calculations to enable lattice QCD simulations to uncover signals of new, ’Beyond the Standard Model’ physics in experimental data. We principally focus on improvements for simulations describing the physically interesting decays of heavy B-mesons. In doing so, we will develop optimised numerical integration tools for use more widely in scientific calculations on a variety of supercomputer architectures.
