The mass distribution of quark matter
arXiv:hep-ph/0606076 · doi:10.1103/PhysRevC.75.034910
Abstract
We analyze lattice QCD results on the equation of state in terms of infinitely many non-interacting massive ideal gas components. 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.
