Effective theory for QCD at finite temperature and density from strong coupling expansion
- QCD at finite temperature and denisty remains intractable by Monte Carlo simulations for quark chemical potentials m >∼T. It has been a long standing problem to derive effective theories from QCD which describe the phase structure of the former with controlled errors. We propose a solution to this problem by a combination of analytical and numerical methods. Starting from lattice QCD with in Wilson’s formulation, we derive an effective action in terms of Polyakov loops by means of combined strong coupling and hopping expansions. The theory correctly reflects the centre-symmetry in the pure gauge limit and its breaking through quarks. It is valid for heavy quarks and lattices up to Nt ∼ 6. Its sign problem can be solved and we are able to calculate the deconfinement transition of QCD with heavy quarks for all chemical potentials.
