The Phase Diagram of Hadronic Matter

Understand

We interpret the phase structure of hadronic matter in terms of the basic dynamical and geometrical features of hadrons.

• Increasing the density of constituents of finite spatial extension, by increasing the temperature T or the baryochemical potential mu, eventually "fills the box" and eliminates the physical vacuum.
• We determine the corresponding transition as function of T and mu through percolation theory.
• At low baryon density, this means a fusion of overlapping mesonic bags to one large bag, while at high baryon density, hard core repulsion restricts the spatial mobility of baryons.
