Five-Brane Configurations, Conformal Field Theories and the Strong-Coupling Problem
E. Kiritsis, C. Kounnas, P. M. Petropoulos +1
Decoupling limits of physical interest occur in regions of space--time where the string coupling diverges. This is illustrated in the celebrated example of five-branes. There are s…
Towards the classification of Z2XZ2 fermionic models
A. E. Faraggi, C. Kounnas, S. E. M. Nooij +1
We develop a formalism that allows a complete classification of four-dimensional Z2XZ2 heterotic string models. Three generation models in a sub-class of these compactifications ar…
Non-factorisable metrics and Gauss--Bonnet terms in higher dimensions
B. Abdesselam, A. Chakrabarti, J. Rizos +1
An iterative construction of higher order Einstein tensors for a maximally Gauss-Bonnet extended gravitational Lagrangian was introduced in a previous paper. Here the formalism is…
