We find that the entire pressure-temperature curve can be described by a temperature independent mass distribution at vanishing chemical potential. We collect strong indications for a mass gap in this distribution, conjectured to be related confinement.4 pages 3 figures LateXHigh Energy Physics - Phenomenologytext
