The Search for Unification.

Alon Faraggi (Liverpool University)


The quest for unification is a prevailing theme is physics, from Newton who unified terrestrial and celestial mechanics, to modern day efforts to synthesize general relativity and quantum mechanics. I will describe contemporary work on two fronts in this direction. The first is the construction of phenomenological heterotic-string models and the study of a particular class that produced solely the spectrum of the Minimal Supersymmetric Standard Model in their low energy effective field theory. The second front is an attempt to identify a fundamental principle underlying quantum gravity, in the context of the equivalence postulate of quantum mechanics. The 750 GeV di-photon excess as a possible signature of a string derived Z' model will be discussed. The presentation will be non--technical and suitable for a general audience.
