      abstract     = {Studies of the spin, parity and tensor couplings of the
                      Higgs boson in the $H\rightarrow ZZ^*\rightarrow 4\ell$,
                      $H\rightarrow WW^* \rightarrow e\nu\mu\nu$ and $H\rightarrow
                      \gamma \gamma$ decay processes at the LHC are presented. The
                      investigations are based on $25$ fb$^{-1}$ of $pp$ collision
                      data collected by the ATLAS experiment at $\sqrt{ s} = 7$
                      TeV and $\sqrt{ s }= 8$ TeV. The Standard Model (SM) Higgs
                      boson hypothesis, corresponding to the quantum numbers $J
                      ^P=0^+$, is tested against several alternative spin
                      scenarios, including non-SM spin-0 and spin-2 models with
                      universal and non-universal couplings to fermions and vector
                      bosons. All tested alternative models are excluded in favour
                      of the SM Higgs boson hypothesis at more than 99.9\%
                      confidence level. Using the $H\rightarrow ZZ^*\rightarrow
                      4\ell$ and $H\rightarrow WW^* \rightarrow e\nu\mu\nu$
                      decays, the tensor structure of the $HVV$ interaction in the
                      spin-0 hypothesis is also investigated. The observed
                      distributions of variables sensitive to the non-SM tensor
                      couplings are compatible with the SM predictions and
                      constraints on the non-SM couplings are derived.},
