Superstring Extension of the Standard Model and Gravitation

  title={Superstring Extension of the Standard Model and Gravitation},
  author={Costas Kounnas},
Some of the four-dimensional Superstring solutions provide a consistent framework for a Supersymmetric Unication of all interactions including gravity. A class of them extends successfully the validity of the standard model up to the string scaleO(10 17 ) GeV . We stress the importance of string corrections which are relevant for low energyO(1) TeV predictions of gauge and Yukawa couplings as well as the spectrum of the supersymmetric particles after supersymmetry breaking.
