Description
At the present time study of the $QCD$ phase diagram in the $(T, \mu)$ plane from LQCD calculations is very difficult due to the sign problem. On the other hand, $QC_2D$ has no sign problem, thus providing an opportunity to investigate properties of $QGP$ from the first principles. In this talk we present the results of lattice simulation of $QC_2D$ with two flavors of staggered fermions and non-zero quark chemical potential. Dependencies of the Polyakov loop, chiral condensate and baryon number density on $\mu_q$ were studied. We found, that raising of the baryon chemical potential leads to the chiral symmetry restoration. At small $\mu_q$ our results for the baryon density agree with ChPT predictions.
