Abstract
Employing a quantum-chromodynamic framework, we study the existence of quark-antiquark pairs, in addition to the usual valence quarks, within the rest frame of baryons. The structure of such a quark sea is discussed and an estimate of its strength is made using the MIT bag model. A significant amount of sea is found, and its effect on calculated properties of hadrons is 20-30%.Keywords
