Professor Liuti´s research involves theoretical studies of the quark and gluon internal dynamics of the proton. The fundamental interactions of quarks and gluons are governed by the beautifully concise Lagrangian of quantum chromodynamics (QCD), however, to be able to understand the mechanisms generating the proton mass, spin and mechanical properties in terms of quarks and gluons is one of the biggest challenges in physics today. Professor Liuti's work has been focused on understanding how the nucleon gets its spin from its fundamental degrees of freedom: is the orbital motion of quarks and gluons relevant and how do we describe it in QCD?  The theoretical tools that allows us to obtain information on angular momentum and other mechanical properties including pressure and shear are the 3D parton distributions, or the Wigner distributions at the femtoscale.  A new generation of current and planned experiments at the future Electron Ion Collider (EIC) could in principle allow us to incorporate all the information from data and phenomenology into a tomographic image connecting the deepest part of the quantum world with what we see as everyday matter around us. Accessing this new type of knowledge has far reaching consequences as it could even impact our understanding of the interior of neutron stars.
