Chromodynamika kwantowa a podłużna i poprzeczna struktura materii kwarkowo-gluonowej

Principal Investigator: dr hab. Krzysztof Kutak. The NCN founded project addresses study of properties of final and initial state of high energu collisions. Namely the physics of gluon saturation and physics of quark gluon plasma. As a probe of these dense systems hard probes like jets and electroweak bozons are used.
