J/psi production and polarization
  The study of the production of heavy quarkonium is crucial for a thorough understanding of Quantum Chromodynamics (QCD). This note reports the measurements of the J\psi, \chi_c and double charm production cross section, and discusses the prospects for the J/psi polarization at LHCb.
