Study of high energy hadronic interactions


The purpose of the pro ject is to study the high-energy (Ge V~Te V) hadron- hadron, hadron-nucleus and nucleus-nucleus interactions, in order to clarify i) the nature and prop¬erties of the nuclear matter, its forms of excitation and its new state under high-density and high-temerature conditions, the quark-gluon plasma; and ii) the quark-gluon confine¬ment in hadrons, interactions of the latter and the properties of QCD vacuum. This study faces with the problem of describing strongly-interacting many-body systems controlled by a relativistic dynamics, to which no fundamental and tractable theory is available yet. Within this context, the elaboration of phenomenological models is crucial as an inter¬mediate step toward this direction. Simultaneously, a deeper understanding of certain properties of hadronic matter such as quark confinement and dynamical chiral symmetry breaking, from the first principIes of QCD, is fundamental. Specifically, problems treated in the project are i) Lattice QCD simulations; ii) Effective field theories; iii) Models for elastic, inelastic and diffrative collisions of hadrons; iv Models of hadrons (Skyrmions and bags); v) production and suppression of strangeness and charm in hadronic matter; vi Transport phenomena, relativistic hydrodynamics and phase transitions in QCD.
