This paper presents a high-precision calculation of the hadronic vacuum polarisation (HVP) contribution to the muon anomaly, $ a_\mu $, using lattice quantum chromodynamics (QCD). The result is a significant improvement over previous calculations, reducing uncertainties by 40%. The calculation involves large-scale lattice QCD simulations on finer lattices, allowing for more accurate continuum extrapolation. A small, long-distance contribution is included using experimental data from low-energy regimes where measurements agree. Combined with other standard model contributions, the result leads to a prediction that differs from the measurement of $ a_\mu $ by only 0.9 standard deviations, validating the standard model to 0.37 ppm. The muon is a short-lived particle with a magnetic dipole moment proportional to its spin and charge, and inversely proportional to its mass. The anomalous magnetic moment $ a_\mu $ is a small correction to the Dirac value of 2, and is influenced by quantum corrections from the strong interaction, particularly the HVP contribution. The HVP contribution is the dominant source of uncertainty in the calculation of $ a_\mu $, and this study reduces that uncertainty to below half a percent. The calculation involves a detailed analysis of various uncertainties, including statistical uncertainties, finite spatial and temporal size corrections, continuum extrapolation, and isospin-breaking effects. The study uses a combination of lattice QCD and data-driven methods to determine the HVP contribution, and the results are compared with other lattice and data-driven calculations. The results show good agreement with previous lattice calculations and highlight the importance of precise measurements and theoretical calculations in understanding the muon anomaly. The study also discusses the implications of the results for the standard model and the broader field of quantum field theory. The high precision of the calculation, combined with other standard model contributions, provides a prediction for $ a_\mu $ with a precision of 0.32 ppm, which is in agreement with experimental measurements within one standard deviation. The results demonstrate the success of the standard model in describing the muon anomaly and highlight the importance of continued research in this area.This paper presents a high-precision calculation of the hadronic vacuum polarisation (HVP) contribution to the muon anomaly, $ a_\mu $, using lattice quantum chromodynamics (QCD).
