IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishExact renormalization group techniques are applied to the mass deformed N = 4 supersymmetric Yang{Mills theory, viewed as a regularized N = 2 model. The solution of the flow equation, in case of dominance of the potential term, reproduces the one-loop (perturbatively exact) expression for the eective action of N = 2 supersymmetric Yang-Mills theory, when the regularizing mass, M, reaches the value of the dynamical cutoff. One speculates about the way in which further nonperturbative contributions (instanton eects) may be accounted for.
