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 root s = 7 TeV with ALICE at the LHC.

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 root s = 7 TeV with ALICE at the LHC. Electrons were measured in the transverse momentum range 0.5 < p(t) < 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
