Figure 2

Deviation of the measured $E$/$p$ from the expected $\langle$$E$/$p$$\rangle$ of electrons divided by the $E$/$p$ resolution ($n_{\sigma}^{\rm{EMCal}}$) for tracks in the $p_{\rm T}$ interval 8-10 GeV/$c$ in semi-central (20-40% centrality class) Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV. Electron and hadron candidates are selected with the TPC d$E$/d$x$ by requiring $-$1 $< $ $n_{\sigma}^{\rm{TPC}}$ $< $ 3 and $-$5 $< $ $n_{\sigma}^{\rm{TPC}}$ $< $ $-$3.5, respectively.
