Heavy flavour production in pp collisions and intrinsic quark components   in proton
  The LHC data on the forward heavy flavour hadron production can be a new unique source for estimation of intrinsic heavy quark contributions to the proton. We discuss in detail the D-meson production in pp collisions at the LHC including the intrinsic charm in the proton. We present also some predictions for the K-meson production in the pp collision at the initial energies 158 GeV and 7 TeV made within the perturbative QCD including the intrinsic strangeness in the proton that can be verified in the NA61 experiment and at LHC.
