Large $N_c$ behaviour of lattice QCD in the heavy dense regime

Understand

Combining strong coupling and hopping expansion one can derive a dimensionally reduced effective theory of lattice QCD.

• This theory has a reduced sign problem, is amenable to analytic evaluation and was successfully used to study the cold and dense regime of QCD for sufficiently heavy quarks.
• We show results from the evaluation of the effective theory for arbitrary $N_c$ up to $\kappa^4$.
• The inclusion of gauge corrections is also investigated.
