Separation power of hadron identification in the ITS, TPC, TOF, and HMPID as a function of $\pt$ at midrapidity. The left (right) panel shows the separation of pions and kaons (kaons and protons), expressed as the distance between the peaks divided by the resolution for the pion and the kaon, respectively, averaged over $|\eta|< 0.5$. For the TPC, an additional curve is shown in a narrower $\eta$ region. The lower panels show the range over which the different ALICE detector systems have a separation power of more than $2\sigma$.
