# Robust Determination of the Higgs Couplings: Power to the Data

@article{Corbett2013RobustDO, title={Robust Determination of the Higgs Couplings: Power to the Data}, author={Tyler Corbett and Oscar J. P. {\'E}boli and Juan Gonzalez-Fraile and Maria Concepcion Gonzalez-Garcia}, journal={Physical Review D}, year={2013}, volume={87}, pages={015022} }

We study the indirect effects of new physics on the phenomenology of the recently discovered “Higgs-like” particle. In a model independent framework these effects can be parametrized in terms of an effective Lagrangian at the electroweak scale. In a theory in which the SU(2)L ×U(1)Y gauge symmetry is linearly realized they appear at lowest order as dimension–six operators, containing all the SM fields including the light scalar doublet, with unknown coefficients. We discuss the choice of… Expand
