  In the present paper we explore various dynamical scenarios for New Physics
(NP) which could be generated by very heavy particles and observed in the form
of non-standard "low energy" interactions affecting the scalar sector, the
gauge bosons and the quarks of the third family. Such interactions have been
previously expressed in terms of 48 CP-conserving gauge invariant operators. We
show that each scenario is characterized by a specific subset of such
operators. Thus, if some traces of NP are ever found in the experimental data,
then the comparison with the predictions of the various scenarios, should be
able to guide the search towards the underlying dynamics generating it.
