Bottom Up Meets Heterotic Strings
arXiv:hep-th/0412066
Abstract
In this talk we argue that a certain class of heterotic orbifolds can be the underlying fundamental theory for recently studied field theory GUTs. In addition we demonstrate that symmetric heterotic Z2 times Z2 orbifolds can give rise to three generation models if quantised Wilson lines are switched on.
Based on talks given by A. Wingerter at String Phenomenology 2004, Ann Arbor, 1--6 August 2004, and by S. Forste at the 37th International Symposium Ahrenshoop on the Theory of Elementary Particles, Berlin, 23--27 August 2004
