A method to extract fs/fd and similar ratios from exclusive semi-leptonic B decays yields a 7% uncertainty constraint using existing measurements.
A lattice QCD+QED strategy is outlined for calculating isospin-breaking effects in inclusive tau decays to support high-precision HVP contributions to muon g-2.
A sampling-based extension of Nevanlinna–Pick interpolation propagates lattice uncertainties into an error estimate that shrinks as more Euclidean data points are added.
Framework for exact and approximate kernel transformations between smeared spectral functions, including systematic error bounds computable from input data.
Lattice QCD yields the Ds to Xs l nu inclusive decay rate in agreement with experiment after full chiral and continuum extrapolations, with few-percent total uncertainty.
