Description
Open heavy-flavour and J/psi production measurements are powerful tools to test pQCD calculations in proton-proton collisions at the new LHC energy regime.
In addition, the measurement of open heavy-flavour and J/psi production in proton-proton collisions provides the necessary reference for the ALICE Pb-Pb program.
The ALICE experiment at the LHC collected proton-proton collisions at sqrt(s)=7 and 2.76 TeV in 2010 and 2011. In this talk, the latest results of open heavy-flavour and J/psi production in proton- proton collisions measured by the ALICE experiment at both mid- and forward rapidity via their various hadronic and leptonic decay channels will be presented. These include, among other topics, the first LHC result on J/psi polarization, multiplicity dependence of J/psi production, D-meson mea-
surement down to low transverse momentum and J/psi production from B-hadron decays. Comparisons with different theoretical models will be discussed as well.
