We assume that the recently observed Higgs-like boson belongs to an SU(2) doublet. Moreover, the departures of its couplings are parametrized by a dimension-six effective Lagrangian with the SU(2) X U(1) symmetry realized linearly. We chose the operator basis in order to take full advantage of the available data, e.g., triple-gauge-boson data and EWPT. The effective lagrangian used in the fit is, for further detail see arXiv:1211.4580

where the dimension-six operators are

For notation and further details see the above reference. The fitting was performed using a chi-square test with the theoretical correlated errors treated by the use of pulls.
