Gravitational corrections to N=2 supersymmetric lagrangians

Sergio Cacciatori, Daniela Zanon

In the framework of special Kahler geometry we consider the supergravity-matter system which emerges on a K3-fibered Calabi-Yau manifold. By applying the rigid limit procedure in t…

Constructive algebraic renormalization of the abelian Higgs-Kibble model

R. Ferrari, P. A. Grassi

We propose an algorithm, based on Algebraic Renormalization, that allows the restoration of Slavnov-Taylor invariance at every order of perturbation expansion for an anomaly-free B…

Comment about UV regularization of basic commutators in string theories

A. Yu. Kamenshchik, I. M. Khalatnikov, M. Martellini

Recently proposed by Hwang, Marnelius and Saltsidis zeta regularization of basic commutators in string theories is generalized to the string models with non-trivial vacuums. It is…

Hard-soft renormalization of the massless Wess-Zumino model

M. Pernici, M. Raciti, F. Riva

We show that in a Wilsonian renormalization scheme with zero-momentum subtraction point the massless Wess-Zumino model satisfies the non-renormalization theorem; the finite renorma…

Geometry and beta-functions for N=2 matter models in two dimensions

Silvia Penati, Andrea Refolli, Alexander Sevrin +1

We study renormalizable nonlinear sigma-models in two dimensions with N=2 supersymmetry described in superspace in terms of chiral and complex linear superfields. The geometrical s…

Wilsonian Flow and Mass-Independent Renormalization

M. Pernici, M. Raciti

We derive the Gell-Mann and Low renormalization group equation in the Wilsonian approach to renormalization of massless in four dimensions, as a particular case of a non-lin…

The rigid limit in Special Kahler geometry; From K3-fibrations to Special Riemann surfaces: a detailed case study

Marco Billo, Frederik Denef, Pietro Fre +4

The limiting procedure of special Kahler manifolds to their rigid limit is studied for moduli spaces of Calabi-Yau manifolds in the neighbourhood of certain singularities. In two e…

Topological Yang-Mills cohomology in pure Yang-Mills Theory

A. Accardi, A. Belli, M. Martellini +1

Using the first order formalism (BFYM) of the Yang-Mills theory we show that it displays an embedded topological sector corresponding to the field content of the Topological Yang-M…

Spin effects on the cyclotron frequency for a Dirac electron

Giovanni Salesi, Erasmo Recami

The Barut--Zanghi (BZ) theory can be regarded as the most satisfactory picture of a classical spinning electron and constitutes a natural "classical limit" of the Dirac equation. T…

Special geometry of Calabi-Yau compactifications near a rigid limit

Marco Billo, Frederik Denef, Pietro Fre +4

We discuss, in the framework of special Kahler geometry, some aspects of the "rigid limit" of type IIB string theory compactified on a Calabi-Yau threefold. We outline the general…

Non-transversal colliding singularities in F-theory

S. Penati, A. Santambrogio, D. Zanon

This is a short introduction to the study of compactifications of F-theory on elliptic Calabi-Yau threefolds near colliding singularities. In particular we consider the case of non…

Duality in N=2 nonlinear sigma-models

S. Penati, A. Refolli, A. Van Proeyen +1

We consider N=2 supersymmetric nonlinear sigma-models in two dimensions defined in terms of the nonminimal scalar multiplet. We compute in superspace the one-loop beta function and…
