Latest QCD results on Pb-Pb collisions from CMS

Although CMS is a LHC experiment designed to study pp collisions it is well suited to study heavy-ion collisions too. In this talk we present some of the results from CMS, restricting on anisotropical particle emission and jets. The anisotropy is measured using four methods with different sensitivities to the non-flow correlations and initial geometrical fluctuations. The jets are analysed using two-particle azimuthal correlations. These two-particle correlations are also used to extract Fourier coefficients which quantify the magnitude of the anisotropy. The strong CMS magnet allowed to measure accurately particle anisotropy up to 60 GeV/c. Beside transverse momentum dependence the results are presented {\it vs} centrality too.
