We present a phase diagram for SU(3) lattice gauge theory with 695 MeV dynamical
staggered fermions, obtained from effective Polyakov line actions. The derivation is via the method of relative weights and the effective theories are solved at finite chemical potential by mean field theory. We find a phase transition line in the plane of temperature and chemical potential and compare it to...
We study the structure of hybrid static potential flux tubes in SU(2) Lattice Yang-Mills-theory. To this end, we compute the square of the chromoelectric and chromomagnetic field strength components for different hybrid static potential quantum numbers. We find clear indications that the gluonic distribution is different compared to the ordinary static potential and present corresponding first results.
