Dilaton Interactions in QCD and in the Electroweak Sector of the Standard Model

摘要

We overview the structure of the effective action involving a dilaton and a Higgs in the Standard Model, which has been computed recently for the neutral currents sector. We discuss the role of the dilatation current (J_D) and of an effective degree of freedom appearing in the J_DVV' correlator, with V any neutral current, which can be interpreted as a Nambu-Goldstone mode generated by the anomalous breaking of the dilatation symmetry.
