Abstract
The ALICE TPC provides excellent charged particle tracking to study pp and Pb-Pb collisions at LHC. The TPC allows also particle identification (PID) via the measurement of the specific ionisation dE/dx. At high p(T) (p(T) > 3 GeV/c) this is accomplished in the region of the relativistic rise of the energy loss, and provides a measurement of the yields of charged pions, kaons; and protons. Here, we present the performance of such an analysis in pp collisions at 7 TeV for charged pions up to 10 GeV/c. On the relativistic rise, statistical PID can be used to evaluate the yields for pions, protons and kaons for p(T) > 3 GeV/c. Here, we show first performance results from such an analysis for charged pions up to 10 GeV/c.
