On the Structure of Noncommutative N=2 Super Yang-Mills Theory
Diego Bellisai, Jose' M. Isidro, Marco Matone
We show that the recently proposed formulation of noncommutative N=2 Super Yang-Mills theory implies that the commutative and noncommutative effective coupling constants τ(u) and τ…
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…
Non-holomorphic terms in N=2 SUSY Wilsonian actions and RG equation
Diego Bellisai, Francesco Fucito, Marco Matone +1
In this paper we first investigate the Ansatz of one of the present authors for K(Ψ,\barΨ), the adimensional modular invariant non-holomorphic correction to the Wilsonian effective…
Fermionic zero-modes around string solitons
Diego Bellisai
In presence of string solitons, index theorems for the generalised Dirac operators have to be revisited. We show that in supersymmetric configurations the fermionic operators decou…
