We discuss various methods for placing limits on additional couplings, including measurement of the partial width, threshold scans, and asymmetries constructed from angular observables. We find that only the asymmetries provide a definitive test of additional couplings. We further estimate the significances they provide.3 pages, 3 figures, Proceedings of The European Physical Society Conference on High Energy Physics, 19-25 July 2007High Energy Physics - Phenomenologytext
