We describe transverse spectra as well as azimuthal anisotropy ($v_2$) ofcharged hadrons stemming from various centrality PbPb collisions at $\sqrt s$ =2.76 ATeV analytically in a `soft + hard' model. In this model, we propose thathadron yields produced in heavy-ion collisions are simply the sum of yieldsstemming from jets (hard yields) and yields stemming from the Quark-GluonPlasma (soft yields). The hadron spectra in both types of yields areapproximated by the Tsallis distribution. It is found that the anisotropydecreases for more central collisions.
