The investigations are based on 25 fb(-1) of pp collision data collected by the ATLAS experiment at root s = 7 TeV and root 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 -> ZZ* -> 4l and H -> WW* -> e nu $\mu$nu. decays, the tensor structure of the interaction between the spin-0 boson and the SM vector bosons 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.", optnote="WOS:000366310400001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2496), last updated on Thu, 07 Jan 2016 16:01:25 +0000", issn="1434-6044", doi="10.1140/epjc/s10052-015-3685-1", opturl="http://arxiv.org/abs/1506.05669", opturl="https://doi.org/10.1140/epjc/s10052-015-3685-1", archivePrefix="arXiv", eprint="1506.05669", language="English" }
