Lectures on Superstring Phenomenology
The phenomenological aspects of string theory are briefly reviewed. Emphasis is given to the status of 4D string model building, effective Lagrangians, model independent results, supersymmetry breaking and duality symmetries. Lectures Given at V Latin American Workshop on Particles and Fields, Puebla, Mexico, November 1995 CERN-TH/96-65 March 1996
متن کاملSuperstring Phenomenology: An Overview
Before 1995 there were five consistent string theories, all existing in ten dimensions, namely, type I open strings with gauge symmetry SO(32), type IIA and IIB closed strings and the two closed heterotic strings with gauge symmetries E8 ⊗ E8 and SO(32). Out of these five theories, the one that attracted most of the attention was the heterotic E8 ⊗ E8 theory because it was the most promising fo...
متن کاملRecent Trends in Superstring Phenomenology
We review for non-experts possible phenomenological scenari in String Theory. In particular we focus on vacuum configurations with intersecting and/or magnetized unoriented D-branes. We will show how a TeV scale tension may be compatible with the existence of Large Extra Dimensions and how anomalous U(1)’s can give rise to interesting signatures at LHC or in cosmic rays. Finally, we discuss uno...
متن کاملRecent Developments in Superstring Phenomenology
Recent developments in superstring phenomenology are summarized on a non-technical level. Talk presented at the XXVIIth Rencontre de Moriond on Electroweak Interactions and Unified Theories. CERN-TH.6492/92 May 1992 Superstring theory [1] is still today the only candidate theory incorporating a consistent quantum gravity. That is, it provides a prescription of how to sensibly compute loop corre...
متن کاملNew and Improved Superstring Phenomenology
Recent developments in string theory have important implications for cosmology. Topics discussed here are inflation, the cosmological constant, smoothing of cosmological singularities, and dark matter from parallel universes. Talk presented at the International Workshop on Particle Physics and the Early Universe (COSMO-98), 15-20 Nov, Asilomar, Monterey, CA. Lost in (Moduli) Space The duality r...
