Summary
This lattice QCD study presents precision calculations of strange and charm quark contributions to the muon's anomalous magnetic moment using twisted-mass fermion formulations. Employing gauge configurations at five lattice spacings with continuum limit extrapolation, the authors report results that align well with findings from other lattice collaborations, contributing to efforts to understand discrepancies between theoretical and experimental muon g−2 measurements.
UK applicability
This is a fundamental physics calculation with no direct application to UK farming systems, soil health, or food production. The record appears to have been incorrectly catalogued in Vitagri's Pulse Brain.
Key measures
Hadronic vacuum polarisation (HVP) contribution to muon anomalous magnetic moment; strange quark contribution (10^−10 units); charm quark contribution (10^−10 units)
Outcomes reported
The study calculated the hadronic vacuum polarisation contribution of strange and charm quarks to the anomalous magnetic moment of the muon using lattice QCD simulations. Results obtained were a_μ^HVP(s) = (53.57 ± 0.63) × 10^−10 for strange quarks and a_μ^HVP(c) = (14.56 ± 0.13) × 10^−10 for charm quarks.
