v₂ of charged hadrons in a`soft + hard' model for PbPb collisions at √ s = 2.76 ATeV

الأصل · EN

We describe transverse spectra as well as azimuthal anisotropy (v₂) of charged hadrons stemming from various centrality PbPb collisions at √ s = 2.76 ATeV analytically in a `soft + hard' model. In this model, we propose that hadron yields produced in heavy-ion collisions are simply the sum of yields stemming from jets (hard yields) and yields stemming from the Quark-Gluon Plasma (soft yields). The hadron spectra in both types of yields are approximated by the Tsallis distribution. It is found that the anisotropy decreases for more central collisions.
