Understanding of short-range correlations (SRCs) between nucleons has been one of the most elusive goals for nuclear physics over the last decades since these correlations play important roles in many domains, such as nuclear structure, nuclear reactions, and astrophysics. Recently, high-energy electron- and proton-scattering experiments demonstrated the existence of nucleons forming short-range correlated pairs with high relative momentum, much larger than the Fermi momentum of the nuclear system, and low c.m. momentum. These kinematical characteristics have also been confirmed by a recent experiment performed at Dubna with 12C projectiles accelerated at high kinetic energies and using the inverse kinematics technique to identify the reaction products. In this seminar, I will summarize the results obtained from these experiments and how these new features have been implemented in the dynamical reaction model INCL developed at CEA. This new development allows us to improve the INCL predictions for spallation and fragmentation reactions, in particular, the predictions for nucleon knock-out cross sections as well as the production cross sections of other nuclear residues. Additionally, we also expect to improve the results obtained for neutrino-nucleus interactions.
