英文摘要	We present the first lattice QCD calculation of the distribution amplitudes of longitudinally and transversely polarized vector mesons K* and phi using large momentum effective theory. We use the clover fermion action on three ensembles with 2 + 1 + 1 flavors of highly improved staggered quarks action, generated by the MIMD Lattice Computation Collaboration, at physical pion mass and {0.06; 0.09; 0.12} fm lattice spacings and choose three different hadron momenta P-z = {1.29; 1.72; 2.15} GeV. The resulting (l)attice matrix elements are nonperturbatively renormalized in a recently proposed hybrid scheme. An extrapolation to the continuum and infinite momentum limit is carried out. We find that, while the longitudinal distribution amplitudes tend to be close to the asymptotic form, the transverse ones deviate rather significantly from the asymptotic form. Our final results provide crucial ab initio theory inputs for analyzing pertinent exclusive processes.
