Lattice QCD Calculation of -dependent Meson Distribution Amplitudes at Physical Pion Mass with Threshold Logarithm Resummation
Ian Cloet, Xiang Gao, Swagato Mukherjee +5
We present a lattice quantum chromodynamics (QCD) calculation of the -dependent pion and kaon distribution amplitudes (DA) in the framework of large momentum effective theory. T…
