Abstract: The SM- like Higgs boson, discovered by the CMS and ATLAS experiments at the LHC, opens a new window to search for beyond SM physics. Di-Higgs production at colliders can be used to search for new physics especially in the high invariant mass region of Higgs pair either for resonant or non-resonant searches. I present the results of search for large extra dimensions looking at di-Higgs channel in proton-proton collisions. Different techniques such as fat-jet approach to reconstruct jets are applied in the boosted regime for the Higgs candidates. Finally, different observables are employed to set limits on the model parameters.
