Their characteristics are sensitive to the nucleon-nucleon interaction at short distances and are therefore eminently suitable for probing cold-dense nuclear matter, such as that which exists in neutron stars, here on the earth. Although studied for many years, only recently, with the reach of high-energy high-luminosity electron and proton beams, the experiments finally reveal the details of short-range nucleon-nucleon correlations. We review the experimental results and discuss their wide range implications for atomic, nuclear, and astrophysics, including neutrino-nucleus scattering, the EMC effect, the NuTeV anomaly, the nuclear symmetry energy, and more. Эли Пезецки (Тель-Авивский университет, Израиль), Гай Рон (Иерусалимский еврейский университет, Израиль) «Study of Short Range Correlation in Nuclei with Hadron Beams» Abstract We discuss the physics motivation and open questions, which show the need for a high statistics next generation of experimental studies of short-range correlations in nuclei. We review the possibility of us-ing a few GeV/c proton beams for such measurements and the possi-ble layout of the experiment.
