Abstract

The pT-differential production cross section of electrons from semileptonic decays of heavy-flavor hadrons has been measured at mid-rapidity in proton-proton collisions at √s = 2.76 TeV in the trans- verse momentum range 0.5 < pT < 12 GeV/c with the ALICE detector at the LHC. The analysis was performed using minimum bias events and events triggered by the electromagnetic calorime- ter. Predictions from perturbative QCD calculations agree with the data within the theoretical and experimental uncertainties.
