#### Hadronic, nuclear and atomic physics

Nuclear physics is concerned with the discovery and understanding of the fundamental characteristics of atomic nuclei such as their masses and sizes. In spite of many years of research, a precise understanding of the neutron distribution in nuclei is still lacking. This is a problem with far-reaching implications, since nuclear physics plays an important role in the study of heavy ion collisions and in the equation of state of neutron-rich matter, therefore influencing different aspects of stellar nucleosynthesis, supernovae explosions and the structure and dynamics of neutron stars.

Another important problem of current nuclear physics is related to Quantum Chromodynamics(QCD). Being the theory which governs the interactions between the basic building blocks of matter, quarks and gluons, it is also responsible for all the states of matter in the universe. Nevertheless, due to the large complexity of the quark-gluon dynamics, one cannot obtain analytical solutions of QCD in the energy regime relevant for nuclear physics, and approximate methods have to be used to obtain solutions of QCD at low energies.

##### ICCUB Contribution

Nuclear physicists at ICCUB are actively participating in studies of neutron-rich nuclei, a research which is closely related to that conducted on the topics of nuclear equation of state and its astrophysical applications. They have also benefited from the computational power offered by the most modern supercomputers (Tungsten, Hopper, Curie, Mare Nostrum, etc.). This has allowed them to perform large dynamical simulations of light nuclei and hypernuclei.
