Renormalization of the Non-Linear Sigma Model in Four Dimensions. A two-loop example

Ruggero Ferrari, Andrea Quadri

The renormalization procedure of the non-linear SU(2) sigma model in D=4 proposed in hep-th/0504023 and hep-th/0506220 is here tested in a truly non-trivial case where the non-line…

Rational foundation of GR in terms of statistical mechanic in the AdS/CFT framework

Pedro J. Silva

In this article, we work out the microscopic statistical foundation of the supergravity description of the simplest 1/2 BPS sector in the AdS(5)/CFT(4). Then, all the corresponding…

6D Supersymmetry, Projective Superspace and 4D, N=1 Superfields

S. J. Gates, S. Penati, G. Tartaglino-Mazzucchelli

In this note, we establish the formulation of 6D, N=1 hypermultiplets in terms of 4D chiral-nonminimal (CNM) scalar multiplets. The coupling of these to 6D, N=1 Yang-Mills multiple…

Two-point correlators in the beta-deformed N=4 SYM at the next-to-leading order

Silvia Penati, Alberto Santambrogio, Daniela Zanon

We compute two-point functions of lowest weight operators at the next-to-leading order in the couplings for the beta-deformed N=4 SYM. In particular we focus on the CPO Tr(Phi_1^2)…

Spin in quantum field theory

Stefano Forte

I introduce spin in field theory by emphasizing the close connection between quantum field theory and quantum mechanics. First, I show that the spin-statistics connection can be de…

Exact results in planar N=1 superconformal Yang-Mills theory

Andrea Mauri, Silvia Penati, Alberto Santambrogio +1

In the β-deformed N=4 supersymmetric SU(N) Yang-Mills theory we study the class of operators O_J = Tr(Φ_i^J Φ_k), i\neq k and compute their exact anomalous dimensions for N,J\to\in…

Chern-Simons formulation of three-dimensional gravity with torsion and nonmetricity

Sergio L. Cacciatori, Marco M. Caldarelli, Alex Giacomini +2

We consider various models of three-dimensional gravity with torsion or nonmetricity (metric affine gravity), and show that they can be written as Chern-Simons theories with suitab…

On {\cal N}=1 exact superpotentials from U(N) matrix models

Federico Elmetti, Alberto Santambrogio, Daniela Zanon

In this letter we compute the exact effective superpotential of {\cal N}=1 U(N) supersymmetric gauge theories with N_f fundamental flavors and an arbitrary tree-level polynomial su…

A Weak Power-Counting Theorem for the Renormalization of the Non-Linear Sigma Model in Four Dimensions

Ruggero Ferrari, Andrea Quadri

The formulation of the non-linear sigma model in terms of flat connection allows the construction of a perturbative solution of a local functional equation encoding the underlying…

Revisiting the D1/D5 System or Bubbling in AdS_3

Matteo Boni, Pedro J. Silva

In this article we study the relation between the bubbling construction and the Mathur's microscopic solutions for the D1/D5 system. We have found that the regular near horizon D1/…

Slavnov-Taylor parameterization of Yang-Mills theory with massive fermions in the presence of singlet axial-vector currents

Andrea Quadri

We study the all-order restoration of the Slavnov-Taylor (ST) identities for Yang-Mills theory with massive fermions in the presence of singlet axial-vector currents. By making use…

Endowing the Nonlinear Sigma Model with a Flat Connection Structure: a Way to Renormalization

Ruggero Ferrari

We discuss the quantized theory of a pure-gauge non-abelian vector field (flat connection) as it would appear in a mass term a` la Stueckelberg. However the paper is limited to the…

Scherk-Schwarz Breaking and Intersecting Branes

C. Angelantonj, M. Cardella, N. Irges

We study the effect of Scherk-Schwarz deformations on intersecting branes. Non-chiral fermions in any representation of the Chan-Paton gauge group generically acquire a tree-level…

Euler angles for G2

Sergio L. Cacciatori, Bianca L. Cerchiai, Alberto Della Vedova +2

We provide a simple parametrization for the group G2, which is analogous to the Euler parametrization for SU(2). We show how to obtain the general element of the group in a form em…

Plane waves from double extended spacetimes

S. L. Cacciatori, G. Ortenzi, S. Penati

We study exact string backgrounds (WZW models) generated by nonsemisimple algebras which are obtained as double extensions of generic D--dimensional semisimple algebras. We prove t…

Covariant quantization of N=1/2 SYM theories and supergauge invariance

S. Penati, A. Romagnoni

So far, quantum properties of N=1/2 nonanticommutative (NAC) super Yang--Mills theories have been investigated in the WZ gauge. The gauge independence of the results requires assum…
