Lattice QCD calculation of the pion distribution amplitude with domain wall fermions at physical pion mass

Abstract We present a direct lattice QCD calculation of the x-dependence of the pion distribution amplitude (DA), which is performed using the quasi-DA in large momentum effective theory on a domain-wall fermion ensemble at physical quark masses and spacing a ≈ 0.084 fm. The bare quais-DA matrix ele...
