The unprecedented center-of-mass energy of the proton-proton collisions at the Large Hadron Collider (LHC) enables the production of vector bosons for the first time with a transverse momentum much larger than their rest mass. Hence, the hadronic decay products of W and Z bosons overlap within the detector and special reconstruction techniques are needed. The development of these substructure techniques is of utmost importance for the rich physics program at the LHC and plays a major role in searches for physics beyond the Standard Model. In this seminar, a variety of grooming and substructure techniques are compared in MC simulation and data. Furthermore the search for narrow resonances decaying into pairs of vector bosons (WW, WZ and ZZ) is presented which relies on the successful identification of boosted hadronically decaying vector bosons.
