Description
The flavor asymmetry of the partonic sea offers important insight into the nonperturbative structure of hadrons and the underlying dynamics of QCD. Recent methodological advances in lattice QCD (LQCD) have enabled direct access to the Bjorken-x dependence of hadronic structure, overcoming the long-standing limitation of lattice calculations to a small number of distribution moments. In this talk, I will present a new LQCD result obtained directly at the physical pion mass and provide comparisons with existing phenomenological extractions of sea-quark asymmetry.
