The "Etherworld" and Elementary Particles
Abstract
We discuss a scenario of ``the path to physics at the Planck scale'' where todays theory of the interactions of elementary particles, the so called Standard Model (SM), emerges as a low energy effective theory describing the long distance properties of a subobservable medium existing at the Planck scale, which we call ``ether''. Properties of the ether can only be observable to the extent that they are relevant to characterize the universality class of the totality of systems which exhibit identical low energy behavior. In such a picture the SM must be embedded into a ``Gaussian extended SM'' (GESM), a quantum field theory (QFT) which includes the SM but is extended in such a way that it exhibits a quasi infrared (IR) stable fixed point in all its couplings. Some phenomenological consequences of such a scenario are discussed.
