In spite of the remarkable phenomenological success of QCD as the theory of strong interac- tions, a detailed understanding of the role of quark and gluon degrees of freedom in nuclear matter is still one of the great challenges for the theory. In this respect, ever since the dis- covery that quark and gluons in bound nucleons show momentum distributions noticeably different to those measured in free or less bound nucleons, more than two decades ago, the precise determination of nuclear parton distribution functions (nPDF) has awakened growing attention, driving both increasingly precise and comprehensive nuclear structure functions measurement, and more refined theoretical understanding of the underlying physics
