Searches for diboson resonances at $\sqrt{s}$ = 13 TeV with the ATLAS detector at the LHC

Searches for new diboson resonances, carried out with 3.2\,fb$^{-1}$ of data taken at $\sqrt{s}$ = 13\,TeV with the ATLAS detector at the LHC, are presented. The resonances under consideration are $VV$ ($V$~= $W$ or $Z$), $VH$, $\gamma \gamma$ and $Z \gamma$. Most of the searches do not show any significant excess over the expectation from the SM backgrounds. The largest deviation is seen in the invariant diphoton mass spectrum around $m_{\gamma \gamma} = 750\,$GeV. It corresponds to a significance of $3.9\,\sigma$ (local) and $2.0\,\sigma$ (global) for a spin-0 resonance with a decay width of $\Gamma/m_{\gamma \gamma} = 6\,$\%.
