The ATLAS collaboration reported excesses at around 2 TeV in the di-boson production decaying into hadronic final states. Signal events, in which the decay products of W or Z bosons at high Lorentz boost are contained within single reconstructed jets, are identified using jet substructure techniques.
In this talk I will first discuss the possibility of explaining the excesses with extra gauge bosons in two simple non-Abelian extensions of the Standard Model. In the second part of my talk I will demonstrate the jet substructure method is powerful to probe the Littlest Higgs model with T-parity.
