We study the free energy of static three quark systems in singlet, octet, decuplet and average color channels in the quenched approximation and in 2-flavor QCD at finite temperature. We show that in the high temperature phase singlet and…

We investigate the behaviour of heavy $QQ$- and $QQQ$-free energies in SU(3) pure gauge theory at finite temperature. After stating some general properties of the free energies, we discuss the $QQ$-antitriplet and -sextet channels as well…

We show that the Polyakov loop approaches its asymptotic value at high temperatures {\it from below} in any strongly-coupled gauge theory at large $N_c$ with a dual supergravity description. In these theories the Polyakov loop can be used…
