Hadronic structure from lattice QCD

Abstract

Due to recent computer and algorithmic improvements, lattice calculations of hadronic quantities are now becoming available at pion masses as low as m π ≈ 250 MeV. In this talk I review some of the latest lattice results for electromagnetic form factors of the nucleon, generalised parton distributions of the pion and nucleon, and distribution amplitudes of vector mesons and the nucleon.

Elements of QCD for hadron colliders

“…In principle, yes, and there is ongoing work in this direction (see, e.g., Ref. [28]), however, currently lattice QCD has not reached an accuracy in these calculations that is competitive with the combination of experimental measurements and perturbative QCD analyses that we discuss below.…”
