The second string (phenomenology) revolution
In the past three years our views on how the standard model of particle physics could be embedded into string theory have dramatically changed. The heterotic string is no longer the only possibility for such an embedding and other perturbative (or non-perturbative) corners of M-theory, like Type I or Type II strings seem now possible. It has also been realized that the string scale Ms is not ne...
متن کاملString Phenomenology ∗
These lectures present some topics of string phenomenology and contain two parts. In the first part, I review the possibility of lowering the string scale in the TeV region, that provides a theoretical framework for solving the mass hierarchy problem and unifying all interactions. The apparent weakness of gravity can then be accounted by the existence of large internal dimensions, in the sub-mi...
متن کاملString Phenomenology at the LHC
We consider extensions of the standard model based on open strings ending on D-branes, with gauge bosons due to strings attached to stacks of D-branes and chiral matter due to strings stretching between intersecting D-branes. Assuming that the fundamental string mass scale is in the TeV range and the theory is weakly coupled, we review possible signals of string physics at the Large Hadron Coll...

متن کاملSUSY/SUGRA/String phenomenology
The unification of gauge coupling constants observed in the extrapolation of the high precision LEP data points to the general validity of the ideas of supersymmetry/supergravity and grand unification. This apparant success also then validates the underlying field theoretic approach at least up to the scaleMGUT ≈ 10 GeV. It is then entirely reasonable that one may extrapolate the grand unified ...
