Abstract
Recent results on studies of exotic hadrons at the LHCb experiment are summarised. These are the observation of new resonances decaying to J/$\psi K^{+}$ and J/$\psi\phi$, evidence of a J/$\psi\Lambda$ structure and observation of excited $\Xi^{-}$ states in the $\Xi_{b}^{-}\to J/\psi \Lambda K^{-}$ decay and the study of $B_{s}^{0}\to J/\psi\pi^{+}\pi^{-}K^{+}K^{-}$ decays.

Report
This paper exotic hadron searches at LHCb from the invariant mass from J/Psi and hadron, meson baryon combinations. I would recomed them for publications with some minor corrections.

With the corrects I would recommend the paper for publication.
