Figure 8

(Top) The ${\rm d}E/{\rm d}x$ signal in the ALICE TPC as a function of magnetic rigidity. The expected curves for various particle species are also shown, with the inset panel showing the TOF mass measurement providing additional separation for helium isotopes when $p/Z>$2.3 GeV/$c$. (Bottom) The Time-of-Flight measured in the TOF system as a function of the particle momentum. Tracks are selected with standard cuts inside the pseudorapidity region $|\eta| < 0.5$.
