We revisit the extraction of the triple electroweak gauge boson couplings from the Large Hadron Collider Run I data on the W+W- and W(+/-)Z productions when the analysis also contains additional operators that modify the couplings of the gauge bosons to light quarks and the gauge boson self-energies. We work in the framework of effective Lagrangians where we consider dimension-six operators and perform a global fit to consistently take into account the bounds on these additional operators originating from the electroweak precision data. We show that the constraints on the Wilson coefficients f(B)/Lambda(2) and f(W)/Lambda(2) are modified when we include the additional operators while the limits on f(WWW)/Lambda(2) remain unchanged.
