Open heavy flavour and J/ψ production in proton-proton collisions measured with the ALICE experiment at LHC

Open heavy flavour and J/ψ production are powerful tools to test pQCD predictions in proton-proton (pp) collisions in the new LHC energy regime. In addition, they provide the necessary reference for the ALICE heavy-ion program. The ALICE experiment at the LHC collected pp collision data at s=7 and 2.76 TeV in 2010 and 2011. We report here the latest results of open heavy flavour and J/ψ production at both mid- and forward-rapidity via several hadronic and leptonic decay channels. These include, among other topics, the first LHC result on J/ψ polarization, multiplicity dependence of the J/ψ production, D-meson measurement down to low transverse momentum (pT) and J/ψ production from B-hadron decays. Comparisons with different theoretical models will be discussed as well.
