DOI: 10.1103/physrevlett.127.062002
Abstract: We present the first lattice QCD calculation of the distribution amplitudes of longitudinally and transversely polarized vector mesons K^{*} and ϕ using large momentum effective theory. We use the clover fermion action on three ensembles… read more here.
