The differential production cross section of electrons from semileptonic heavy-flavor hadron decays has been measured at midrapidity (jyj < 0:5) in proton-proton collisions at ffisffiffi p ¼ 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 (jyj < 0:5) in proton-proton collisions at ffisffiffi p ¼ 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.File in questo prodotto:
