002001958 520__ $$aWe review the effective field theory where the Standard Model is extended by higher-dimensional operators. Various existing operator sets (bases) spanning the space of dimension-6 operators are discussed. For the SILH basis and for the Warsaw basis, we derive the map between the Wilson coefficients of dimension-6 operators and the couplings of mass eigenstates in the Lagrangian. We also propose a new parametrization of the space of dimension-6 operators: the so-called Higgs basis. In that basis, the dimension-6 operators that can be best probed by LHC Higgs searches are explicitly separated from the ones strongly constrained by previous experiments. Therefore, the Higgs basis is particularly convenient for leading order effective field theory analyses of the LHC Higgs data.
