Bound Nucleon Form Factors, Quark-Hadron Duality, and Nuclear EMC Effect
Abstract
We discuss the electromagnetic form factors, axial form factors, and structure functions of a bound nucleon 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, we compute the in-medium modification of the bound nucleon form factors in the same framework. Finally, limits on the medium modification of the bound nucleon structure function are obtained using the calculated in-medium electromagnetic form factors and local quark-hadron duality.
