Abstract:
The latest years have seen a resurrection of interest in searches for
exotic states motivated by tantalising observations by Belle and CDF.
Using the data collected at pp collisions at 7 and 8 TeV by the LHCb
experiment we present unambiguous observations of exotic charmonia
hadrons produced in B decays. Most notably, two pentaquark candidates
observed in Lambda_b -> J/psi p K decays are reported.
