Assuming the complete theory is a gauge theory, we determine which effective operators may be generated at tree level, and which are only generated at loop level. The latter are be suppressed by factors of $1/ 16\\pi^2$ and will therefore be quite difficult to detect. In particular, all operators changing the Standard-Model structure of the triple-gauge-vector couplings fall into this category. We also point out that in certain cases, dimension-eight operators may be more important than dimension-six operators. We discuss both the linear and non-linear representation of the Higgs sector.", "revisions": [ { "version": "v5", "updated": "1994-05-18T22:44:51.000Z" } ], "analyses": { "keywords": [ "standard model", "triple-gauge-vector couplings fall", "higgs sector", "tree level", "complete theory" ], "tags": [ "journal article" ], "publication": { "publisher": "Elsevier", "journal": "Nucl.
