Title:     From light nuclei to astrophysics

Abstract: The investigation of light nuclei with ab-initio methods provides an optimal setting to probe our knowledge of nuclear forces. This is even more the case if one considers exotic structures like neutron halos. Today, effective field theory (EFT) provides us with a framework to consistently derive two- and many-body nuclear forces. A joint effort of theory and experiment needs to be taken towards the identification of bound and continuum observables sensitive to the less constrained many-nucleon forces. From the theoretical side, recent efforts have been directed on achieving a unified view of bound and scattering nuclear properties treated on equal footing. This is a fundamental step towards a predictive theory for experiments performed at the radioactive beam facilities.
Here I present our recent achievements on the study of structure properties of halo systems and on continuum electromagnetic responses of light nuclei. Possible applications to nuclear astrophysics are discussed. Finally, I talk about neutrino processes, relevant to the physics of supernovae, studied with the new insights provided by EFT.


Stimulants will be available 15 minutes before the talk.
