Abstract

A model which breaks Bjorken scaling in the deep-inelastic electron-nucleon scattering is presented and compared with the recent data of the MIT-SLAC collaboration and Fermilab. In this model it is assumed that the scaling violation is mainly due to the structure of the hadronic constituents and the transitions of the constituents to their excited states by absorbing a virtual photon. Fitting the formula of the structure function derived from this model to the data, we find the possibility that there exist two excited states with masses about 2.8 and 7-8 GeV.
