Title: 
Quarkonium results at LHCb

Speaker: 
Giulia Manca, University of Cagliari

Abstract: 
LHCb is one of the four LHC experiments which started collecting
pp collisions data at a centre-of-mass energy of 7 and 8 TeV. With
its forward geometry, LHCb is dedicated to the study of
heavy-flavor production and decay. I present the study of the production
ofquarkonia resonances in the data sample collected in the first
three years of data taking, corresponding to more than 2 fb-1.
The production and polarisation of J/psi, psi(2S) and Upsilon are
presented both in proton proton and heavy nuclei
collisions, together with  measurements of associated production
and searches for exotic new states. The results will be
discussed in the framework of different theory models and compared
with other experiments.
