Description
The determination of x-dependent hadron structure from lattice QCD is an increasingly mature endeavour; precision calculations, with control over all systematic uncertainties, hover on the horizon. Precise and accurate lattice calculations will complement the experimental data expected from JLab 12GeV and the future Electron-Ion Collider and shed new light on the internal structure of hadrons. To achieve that goal, however, requires careful analysis of systematic uncertainties in lattice calculations. We propose “window observables” as a quantitative approach to precision benchmarking and cross-validation between and within lattice calculations and global analyses. I will review and motivate two potential window observables and discuss their application to the quark transversity distribution and beyond.
