SU(3) gauge theory with adjoint fermions

Karsch F, Lutgemeier H. SU(3) gauge theory with adjoint fermions. In: Nuclear Physics B - Proceedings Supplements. NUCLEAR PHYSICS B-PROCEEDINGS SUPPLEMENTS. Vol 73. ELSEVIER SCIENCE BV; 1999: 444-446.We analyze the finite temperature phase diagram of QCD with fermions in the adjoint representation. The simulations performed with four dynamical Majorana fermions, which is equivalent to two Dirac fermions, show that the deconfinement and chiral phase transitions occur at two distinct temperature, T-chiral similar or equal to 6.65T(deconf) While the deconfinement transition is first order we find evidence for a continuous chiral transition. We also present potentials for T < T-deconf and T-deconf < T < T-chiral both for fundamental and adjoint fermion-antifermion pairs
