Quest For Unification
Edward Witten
The GUT-based approach to physics has been attractive since it was first put forward close to thirty years ago; it has been enriched by new ideas, notably supersymmetry and strings…
Deconstruction, G_2 Holonomy, and Doublet-Triplet Splitting
Edward Witten
We describe a mechanism for using discrete symmetries to solve the doublet-triplet splitting problem of four-dimensional supersymmetric GUT's. We present two versions of the mechan…
The Cosmological Constant From The Viewpoint Of String Theory
Edward Witten
The mystery of the cosmological constant is probably the most pressing obstacle to significantly improving the models of elementary particle physics derived from string theory. The…
New Perspectives on the Quest for Unification
Edward Witten
Synthesizing older ideas about the 1/N expansion in gauge theory, the quantum mechanics of black holes, and quantum field theory in Anti de Sitter space, a new correspondence betwe…
