Computational physics study demonstrates extraction of heavy-quark masses using one-loop lattice perturbation theory, suggesting effective control over scheme dependence.
FINDING: Fermilab method extracts heavy-quark masses via one-loop lattice perturbation theory, combining lattice QCD with automated perturbative matching to control scheme dependence. | MATH: Heavy-quark mass \( m_Q \) from lattice-determined heavy-strange meson mass \( MH_s \) via \( m_Q = MH_s - Λ̄ + δ m₁₋ₗₒₒₚ \); one-loop matching coefficient \( C_1(μ) \) with renormalization scale \( μ \), scheme dependence enters through \( α_s(μ) \) and lattice spacing \( a \) via \( a⁻¹ \) setting. Key constants: \( α_s(M_Z) ≈ 0.118 \), lattice spacing \( a ≈ 0.09–0.12 \) fm. | CONNECTION: Lattice QCD is a discrete hypercubic lattice — a crystallographic structure with cubic symmetry (space group \( Pm3̄m \)), whose Brillouin zone and root system \( B_3 \) (or \( A_3 \) for staggered fermions) encode the discretized Dirac operator. The one-loop perturbative correction involves sums over lattice momenta that respect this cubic sy Author: Andrew Stewart Caldin, Independent Researcher, UK.
