Event reconstruction and particle identification in the ALICE experiment at the LHC

Event reconstruction and particle identification in the ALICE experiment at the LHC

In these proceedings we give an overview of the methods for track and vertex reconstruction as well as particle identification performed with the ALICE experiment at the LHC. Because of very high particle multiplicities and softness of the particle momentum spectra observed in Pb–Pb collisions, the...
