Exact string backgrounds from WZW models based on non-semi-simple groups
Konstadinos Sfetsos
We formulate WZW models based on a centrally extended version of the Euclidean group in -dimensions. We obtain string backgrounds corresponding to conformal $\s$-models in $D=d^…
Gauging a Non-Semi-Simple WZW Model
Konstadinos Sfetsos
We consider gauged WZW models based on a four dimensional non-semi-simple group. We obtain conformal $\s$-models in spacetime dimensions (with exact central charge ) by…
Environmentally Friendly Renormalization
Denjoe O'Connor, C. R. Stephens
We analyze the renormalization of systems whose effective degrees of freedom are described in terms of fluctuations which are ``environment'' dependent. Relevant environmental para…
Hidden symmetries, special geometry and quaternionic manifolds
B. de Wit, A. Van Proeyen
The moduli space of the Calabi-Yau three-folds, which play a role as superstring ground states, exhibits the same {\em special geometry} that is known from nonlinear sigma models i…
Top Quark Production Cross Section
E. Laenen, J. Smith, W. L. van Neerven
The production rate for top quarks at the Fermilab Tevatron is presented using the exact order corrected cross section and the resummation of the leading soft gluon correct…
Black Hole Evaporation without Information Loss
C. R. Stephens, G. 't Hooft, B. F. Whiting
An approach to black hole quantization is proposed wherein it is assumed that quantum coherence is preserved. A consequence of this is that the Penrose diagram describing gravitati…
