Bose-Einstein condensation of pions in heavy-ion collisions at energies available at the CERN Large Hadron Collider

We analyze in detail the possibility of Bose-Einstein condensation of pions produced in heavy-ion collisions at the beam energy root S-NN = 2.76 TeV. Our approach is based on the chemical nonequilibrium thermal model of hadron production which has been generalized to include separately the contribution from the local zero-momentum state. In order to study both the hadronic multiplicities and the transverse-momentum spectra, we use the Cracow freeze-out model which parameterizes the flow and space-time geometry of the system at freeze-out in a very economic way. Our analysis indicates that about 5% of all pions may form the Bose-Einstein condensate.
