Studying the Universe from deep underground: the LUNA experiment — •Rosanna Depalo — Università degli Studi di Milano and INFN Milano

Nuclear cross sections are crucial ingredients to understand the production of energy inside stars and the synthesis of the elements. In stars, nuclear reactions take place at energies well below the Coulomb barrier. As a result, their cross sections are often too small to be measured in laboratories on the Earths surface, where the signal would be overwhelmed by the environmental background. An effective way to suppress the background is to perform experiments in underground laboratories. The Laboratory for Underground Nuclear Astrophysics (LUNA) is a unique facility located at Gran Sasso National Laboratories (Italy). The extremely low background achieved at LUNA allows to measure nuclear cross sections directly at the energies of astrophysical interest. Over the years, many crucial reactions involved in stellar hydrogen burning as well as Big Bang Nucleosynthesis have been measured at LUNA. The presentation will provide an overview on underground Nuclear Astrophysics and discuss the latest results and future perspectives of the LUNA experiment.
