Quarkonium Production at LHCb

Studies of quarkonia production in the forward region provide important tests of NRQCD. During 2010 and 2011 the LHCb experiment has collected a dataset corresponding to an integrated luminosity of 1.1 fb$^{–1}$ in proton-proton collisions at $\sqrt{s}$ = 7 TeV. We present studies of the production of the $J/\psi$, $\psi$(2S) and $\chi_{c}$ charmonium states as well as bottomonium states. Absolute and relative production rates will be presented and compared to the most recent theoretical predictions available. We also present measurements of double charm production, performed for the first time at a hadron collider.
