European Muon Collaboration effect in deuteron and in three-body nuclei

Abstract
We investigate the European Muon Collaboration (EMC) effect in deuteron and three-body nuclei. The binding and the Fermi motion effects of nucleons are studied in detail. They reduce the structure function ratios from unity by less than 5%. Roles of excess pion are also discussed in connection with the momentum sum rule, which is violated by the binding effect.
