Ads/cft Inspired String Phenomenology
The use of the AdS/CFT correspondence to arrive at quiver gauge field theories is dicussed, focusing on the orbifolded case without supersymmetry. An abelian orbifold with the finite group Zp can give rise to a G = SU (N) p gauge group with chiral fermions and complex scalars in different bi-fundamental representations of G. The precision measurements at the Z resonance suggest the values p = 1...
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 کاملPhenomenology of Twisted Moduli in Type I String Inspired Models
We make a first study of the phenomenological implications of twisted moduli in type I intersecting D5-brane models, focussing on the resulting predictions at the LHC using SOFTSUSY to estimate the Higgs and sparticle spectra. Twisted moduli can play an important role in giving a viable string realisation of sequestering in the limit where supersymmetry breaking comes entirely from the twisted ...

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 ...
