Lattice QCD on quenched 24^3 x 48 lattices yields charged kaon electric polarizability α_E = (0.988 ± 0.534) × 10^{-4} fm³ and charge radius squared 0.3303 ± 0.0028 fm² after physical pion-mass extrapolation.
Analysis of non-perturbative lattice data shows that the inverse problem in LaMET introduces significant uncertainties in parton distributions, especially from harmonics around λ=5-15, and that exact asymptotic decay matters little in the currently applicable x range.
