The ALICE collaboration measured the J/psi photoproduction at LHC in Pb-Pb collisions 

at sqrt_{s}=2.76 TeV. The J/psi is identified via  its dimuon and dielectron decay in the

pseudorapidity region |eta|<0.9. The analysis is based on an event sample corresponding to a luminosity

of 25 micobarn-1. The result is compared to theoretical models for j/psi production.
