The study of the structure of the atomic nucleus and strong nuclear interaction was the first step towards a deeper understanding of matter: from protons and neutrons to quarks, towards the Standard Model of particle physics.
The Frascati National Laboratories have always played a key role in this research field, implementing experiments on site or at other international laboratories, at the frontier of physics knowledge for a deeper understanding of fundamental interactions in the field of nuclear physics and their role in the Universe, from the Big Bang to the present day.
KAOn Nuclear/Nuclei Interaction Studies KAONNIS (KAOn Nuclear/Nuclei Interaction Studies) is an integrated initiative dedicated to the experimental studies of the low-energy kaon-nucleon and kaon-nuclei interactions.
Just a few millionths of a second after the Big Bang, the entire Universe was filled with a plasma composed of quarks and gluons, fundamental entities of matter and nuclear force.
Photoproduction of mesons as a probe of the excitation structure of the nucleon has been exploited since the 1960s. The use of GeV-range energy polarised tagged photon beams at high duty cycle electron accelerators in combination with large acceptance detectors, like CLAS and GLUEX at Jefferson Laboratory, A2 at MAMI, Crystal Barrel at ELSA, GrAAL at ESRF, and LEPS at SPring8, has in recent years put the technique on par with pion scattering to unravel the complex nucleon excitation patterns, allowing for a better understanding ...
Atomic nuclei are made up by protons and neutrons (or nucleons) that together constitute more than 99% of the visible matter in the universe. They are made by elementary constituents, quarks and gluons, whose interactions are described by the Quantum Chromo Dynamics (QCD).
VIP (VIolation of the Pauli exclusion principle) in an international collaboration among 10 Institutions from 5 countries which performs an experimental tests of the Pauli Exclusion Principle (PEP) for electrons and investigates the implications of a possible tiny violation in physics and cosmology.
