Strangeness and charm in QCD matter


Strangeness and charm in QCD matter

Kämpfer, B.; Bluhm, M.

Strangeness and charm degrees of freedom in strongly interacting matter are discussed within a quasi-particle model adjusted to lattice QCD data. While strangeness is found to appear as copious as the other light quark and gluon excitations, the charm quarks are thermally suppressed.
The model allows to extrapolate lattice QCD data to large baryo-chemical potential.
We outline the thermal evolution of matter in the early universe at and slightly after confinement and comment briefly on charm dynamics in relativistic heavy-ion collisions.
