Figure Caption

Efficiencies for the Pb–Pb analysis as a function of transverse momentum. The vertical dashed line indicates the switch of the eID between the TPC and TOF and TOF-only method.

efficiency (ε_rec) of the track reconstruction; efficiency of the TPC electron identification selection (ε_TPCeID)

Detail description

2010 Pb-Pb data set

track selection:

  • standard hfe cuts (SPD kBoth etc.)

electron identification:

  • TOF +/- 3 sigma
  • TPC -0.5 to 3 sigma electron inclusion
