Searches for diboson resonances with ATLAS (VV, VH, HH, excl. diphoton resonance)

This document summarises ATLAS searches for resonances decaying to diboson final states, VV , VH and HH, where V is either a W or a Z boson and H is the Standard Model Higgs boson. The results obtained are based on the full 2015 dataset corresponding to an integrated luminosity of 3.2 fb −1 . No discrepancies with respect to the Standard Model expectations are observed and thus 95% confidence level exclusion limits are set on the production cross section times branching ratios in a number of benchmark scenarios, including Heavy Vector Triplet, Randall-Sundrum Graviton and Extended Higgs sector models.
