The differential production cross section of electrons from semileptonic heavy-flavor hadron decays has been measured at midrapidity (|y|<0.5) in proton-proton collisions at √s=7  TeV with ALICE at the LHC. Electrons were measured in the transverse momentum range 0.5<pt<8  GeV/c. Predictions from a fixed-order perturbative QCD calculation with next-to-leading-log resummation agree with the data within the theoretical and experimental uncertainties.

Abstract

The differential production cross section of electrons from semileptonic heavy-flavor hadron decays has been measured at midrapidity (|y|<0.5) in proton-proton collisions at √s=7  TeV with ALICE at the LHC. Electrons were measured in the transverse momentum range 0.5
