Lattice QCD computation of hadronic tensor yields consistent nucleon Sachs electric form factor and extracts transition form factors to the Roper resonance region for inclusive cross sections.
A sampling-based extension of Nevanlinna–Pick interpolation propagates lattice uncertainties into an error estimate that shrinks as more Euclidean data points are added.
