Description
The Light-Cone Distribution Amplitude (DA) encodes the non-perturbative information of the leading Fock-component of the hadron wave function, therefore required for processes including exclusive hadron production. As the Pseudo-Nambu-Goldstone boson of QCD, nonperturbative structure of the pion is of particular interest. We present a lattice QCD calculation of the pion DA on ensembles with O(a)-improved Wilson fermions on lattice spacings in the range of 0.0483fm-0.0749fm, and pion masses ranging from physical to 440MeV. The Pseudo-Distribution formalism is employed to match the Renormalization Group Invariant (RGI) matrix element to the DA.
