On the Multi-Instanton Measure for Super Yang--Mills Theories
Ugo Bruzzo, Francesco Fucito, Alessandro Tanzini +1
In this paper we revisit the arguments that have led to the proposal of a multi-instanton measure for supersymmetric Yang-Mills theories. We then recall how the moduli space of gau…
Type-I strings on magnetised orbifolds and brane transmutation
C. Angelantonj, I. Antoniadis, E. Dudas +1
In the presence of internal magnetic fields, a D9 brane can acquire a D5 (or anti-D5) R-R charge, and can therefore contribute to the corresponding tadpole. In the resulting vacua,…
Instanton Calculus, Topological Field Theories and N=2 Super Yang-Mills Theories
Diego Bellisai, Francesco Fucito, Alessandro Tanzini +1
The results obtained by Seiberg and Witten for the low-energy Wilsonian effective actions of N=2 supersymmetric theories with gauge group SU(2) are in agreement with instanton comp…
Multi-Instantons, Supersymmetry and Topological Field Theories
D. Bellisai, F. Fucito, A. Tanzini +1
In this letter we argue that instanton-dominated Green's functions in N=2 Super Yang-Mills theories can be equivalently computed either using the so-called constrained instanton me…
Open-string models with broken supersymmetry
A. Sagnotti
I review the salient features of three classes of open-string models with broken supersymmetry. These suffice to exhibit, in relatively simple settings, the two phenomena of ``bran…
