One attempt to reconcile quantum mechanics and general relativity into a theory of everything is string theory, which suggests that electrons and quarks are oscillating one-dimensional 'strings'. String theory remains controversial since it requires unobserved additional dimensions and has yet to make ...

``String Theory in Four Dimensions'' contains a representative collection of papers dealing with various aspects of string phenomenology, including compactifications on smooth manifolds and more general conformal field theories. Together with the lucid introduction by M. Dine, this material gives the re...
A heterotic string theory in four dimensions is constructed by compactifying the Ex E/sup '/ heterotic strings from 26 to 4 dimensions via a manifold T/sup 22//G. The theory is modular invariant. In the low-energy limit, there are three families of chiral fermions with exactly the same ...

Noncritical Dimensions for Critical String Theory: Life Beyond the Calabi-Yau Frontier A recently introduced framework for the compactification of supersymmetric string theory involving noncritical manifolds of complex dimension 2 k + D Crit , k 鈮 1, is reviewed. These higher dimensional manifolds ar...
Coset symmetries in dimensionally reduced bosonic string theory12.10.Dm12.90.+b11.25.MWe discuss the dimensional reduction of various effective actions, particularly that of the closed bosonic string and pure gravity, to two and three dimensions. The result for the closed bosonic string leads to ...
