U-duality and D-brane Combinatorics
B. Pioline, E. Kiritsis
We investigate D-brane instanton contributions to R^4 couplings in any toroidal compactification of type II theories. Starting from the 11D supergravity one-loop four-graviton ampl…
Heterotic/Type-I Duality in D<10 Dimensions, Threshold Corrections and D-Instantons
E. Kiritsis, N. A. Obers
We continue our study of heterotic/type-I duality in D<10 dimensions. We consider the heterotic and type-I theories compactified on tori to lower dimensions. We calculate the speci…
Introduction to Superstring Theory
E. Kiritsis
In these lecture notes, an introduction to superstring theory is presented. Classical strings, covariant and light-cone quantization, supersymmetric strings, anomaly cancelation, c…
Introduction to Non-perturbative String Theory
Elias Kiritsis
These are a set of lectures presented at the CERN-La Plata-Santiago de Compostella School of Physics, La Plata, May 1997. A brief introduction to the non-perturbative structure of…
On threshold corrections in IIB string theory and (p,q) string instantons
Elias Kiritsis, Boris Pioline
We obtain the exact non-perturbative thresholds of terms in IIB string theory compactified to eight and seven dimensions. These thresholds are given by the perturbative tree-…
Perturbative and Non-Perturbative Partial Supersymmetry Breaking; N=4 -> N=2 -> N=1
E. Kiritsis, C. Kounnas
We show the existence of a supersymmetry breaking mechanism in string theory, where N=4 supersymmetry is broken spontaneously to N=2 and N=1 with moduli dependent gravitino masses.…
