Lattice QCD Form Factors for B→Kll Decays — E8 Intelligence Research
Year: 2026
Type: preprint
Abstract: FINDING: The search results are a scattered set of lectures and papers on asymptotic dimension (geometric group theory), asymptotic-preserving numerical methods, scattering amplitudes, and lattice QCD — none directly addressing SU(2)_k modular data or root lattice central extensions. The only concrete mathematical artifact is the arXiv paper on B→Kll form factors from three-flavor lattice QCD. MATH: - Lattice QCD: asqtad improved staggered action (light quarks), clover action (heavy quarks); ensembles at multiple lattice spacings and sea-quark masses; form factors f_+(q²), f_0(q²), f_T(q²) for B→Kll. No explicit equations or constants given in the snippet. - Asymptotic dimension (Bestvina, Dvořák): a coarse geometric invariant, dim_asym(X) = inf{n | X admits a uniformly bounded, n+1-multiple-point-free cover of bounded multiplicity. For planar graphs, dim_asym ≤ 2 (Dvořák). No numerical constants. - Arkani-Hamed: scattering amplitudes via positive Grassmannian, amplituhedron — but no Author: Andrew Stewart Caldin, Independent Researcher, UK.
