【 摘 要 】

We discuss the electromagnetic form factors, axial form factors, and structure functions of a nucleon bound in the quark-meson coupling (QMC) model. Free space nucleon form factors are calculated using the improved cloudy bag model (ICBM). After describing finite nuclei and nuclear matter in the quark-based QMC model, the in-medium modification of the bound nucleon form factors is calculated in the same model. Finally, the bound nucleon structure function is extracted using the calculated in-medium electromagnetic form factors and Bloom-Gilman (quark-hadron) duality.
