Dilatons and Graviton Interactions and the Anomalous Breaking of Scale Invariance in the Standard Model

We discuss the derivation of the TTT correlation function involving insertions of the
energy momementum tensor (EMT's) using free field theory, showing
how to map results in conformal field theory from position space to momentum space.
We develope a regularization that allows to perform such a map.
By tracing the EMT's we derive the cubic interactions of a dilaton to the Standard Model.
In the case of a single insertion of EMT (linear dilaton interaction)
we show that the Standard Model has an infrared coupled
pole which is of phenomenological interest. It describes the dynamics of an effective dilaton interaction
which is Higgs-like and of which we compute the electroweak corrections in its coupling to the neutral currents.
