Canonical Flow in the Space of Gauge Parameters

Andrea Quadri

Gauge dependence of one-particle irreducible (1-PI) amplitudes in SU(N) Yang-Mills theory is shown to be generated by a canonical flow with respect to (w.r.t.) the extended Slavnov…

Modified gravity, the Cascading DGP model and its critical tension

Fulvio Sbisà

We investigate the presence of instabilities in the Cascading DGP model. We start by discussing the problem of the cosmological late time acceleration, and we introduce the modifie…

Renormalization Group Equation for Weakly Power Counting Renormalizable Theories

D. Bettinelli, D. Binosi, A. Quadri

We study the renormalization group flow in weak power counting (WPC) renormalizable theories. The latter are theories which, after being formulated in terms of certain variables, d…

Positive mass theorem in extended supergravities

Masato Nozawa, Tetsuya Shiromizu

Following the Witten-Nester formalism, we present a useful prescription using Weyl spinors towards the positivity of mass. As a generalization of arXiv:1310.1663, we show that some…

Four-point amplitudes in SCQCD

Marta Leoni, Andrea Mauri, Alberto Santambrogio

We compute four-point scattering amplitudes in SCQCD with general external matter configurations using superspace Feynman diagrams, at one loop in t…

Rotating black holes in an expanding universe from fake supergravity

Samuele Chimento, Dietmar Klemm

Using the recipe of arXiv:0902.4814, where all fake supersymmetric backgrounds of matter-coupled fake N=2, d=4 gauged supergravity were classified, we construct dynamical rotating…

The critical tension in the Cascading DGP model

Fulvio Sbisà, Kazuya Koyama

We study the behaviour of weak gravitational fields in the 6D Cascading DGP model using a bulk-based approach. To deal with the ambiguity in the thin limit of branes of codimension…

Quantum Local Symmetry of the D-Dimensional Non-Linear Sigma Model: A Functional Approach

Andrea Quadri

We summarize recent progress on the symmetric subtraction of the Non-Linear Sigma Model in dimensions, based on the validity of a certain Local Functional Equation (LFE) encodi…

Perturbations of Nested Branes With Induced Gravity

Fulvio Sbisà, Kazuya Koyama

We study the behaviour of weak gravitational fields in models where a 4D brane is embedded inside a 5D brane equipped with induced gravity, which in turn is embedded in a 6D spacet…

Fluid dynamics on ultrastatic spacetimes and dual black holes

Dietmar Klemm, Andrea Maiorana

We show that the classification of shearless and incompressible stationary fluid flows on ultrastatic manifolds is equivalent to classifying the isometries of the spatial sections.…

de Sitter tachyons and related topics

Henri Epstein, Ugo Moschella

We present a complete study of a family of tachyonic scalar fields living on the de Sitter universe. We show that for an infinite set of discrete values of the negative squared mas…

Iwasawa nilpotency degree of non compact symmetric cosets in N-extended Supergravity

Sergio Luigi Cacciatori, Bianca Letizia Cerchiai, Sergio Ferrara +1

We analyze the polynomial part of the Iwasawa realization of the coset representative of non compact symmetric Riemannian spaces. We start by studying the role of Kostant's princip…

Four-dimensional black holes with unusual horizons

Dietmar Klemm

We show that in presence of a cosmological constant or, more generally, of a scalar potential, there can exist actually more possibilities for the horizon geometry of a four-dimens…
