Remarks on monopoles in Abelian projected continuum Yang-Mills theories

A. R. Fazio, S. P. Sorella

A possible mechanism accounting for monopole configurations in continuum Yang-Mills theories is discussed. The presence of the gauge fixing term is taken into account.

An integrable noncommutative version of the sine--Gordon system

Marcus T. Grisaru, Silvia Penati

Using the bicomplex approach we discuss a noncommutative system in two--dimensional Euclidean space. It is described by an equation of motion which reduces to the ordinary sine--Go…

The Asymptotic Dynamics of de Sitter Gravity in three Dimensions

Sergio Cacciatori, Dietmar Klemm

We show that the asymptotic dynamics of three-dimensional gravity with positive cosmological constant is described by Euclidean Liouville theory. This provides an explicit example…

Towards a General Theory of Quantized Fields on the Anti-de Sitter Space-Time

Jacques Bros, Henri Epstein, Ugo Moschella

We propose a general framework for studying quantum field theory on the anti-de-Sitter space-time, based on the assumption of positivity of the spectrum of the possible energy oper…

Chern-Simons in the Seiberg-Witten map for non-commutative Abelian gauge theories in 4D

Marco Picariello, Andrea Quadri, Silvio P. Sorella

A cohomological BRST characterization of the Seiberg-Witten (SW) map is given. We prove that the coefficients of the SW map can be identified with elements of the cohomology of the…

Yang-Mills Integrals

G. M. Cicuta, L. Molinari, G. Vernizzi

Two results are presented for reduced Yang-Mills integrals with different symmetry groups and dimensions: the first is a compact integral representation in terms of the relevant va…

Superspace approach to anomalous dimensions in {\cal N}=4 SYM

Silvia Penati, Alberto Santambrogio

In a {\cal N}=1 superspace setup and using dimensional regularization, we give a general and simple prescription to compute anomalous dimensions of composite operators in {\cal N}=…

N=2 Gauge Theories from Wrapped Five-branes

F. Bigazzi, A. L. Cotrone, A. Zaffaroni

We present string duals of four dimensional N=2 pure SU(N) SYM theory. The theory is obtained as the low energy limit of D5-branes wrapped on non-trivial two-cycles. Using seven di…

The asymptotic symmetry of de Sitter spacetime

J. Bros, H. Epstein, U. Moschella

We show how to construct a set of Euclidean conformal correlation functions on the boundary of a de Sitter space from an interacting bulk quantum field theory with a certain asympt…

Some Aspects of the de Sitter/CFT Correspondence

Dietmar Klemm

We discuss several aspects of the proposed correspondence between quantum gravity on de Sitter spaces and Euclidean conformal field theories. The central charge appearing in the as…

N=2 Gauge Theories and Systems with Fractional Branes

M. Petrini, R. Russo, A. Zaffaroni

We analyse the Seiberg Witten curve describing the N=2 gauge theory dual to the supergravity solution with fractional branes. Emphasis is given to those aspects that are related to…

The Diagonal Ghost Equation Ward Identity for Yang-Mills Theories in the Maximal Abelian Gauge

A. R. Fazio, V. E. R. Lemes, M. S. Sarandy +1

A BRST perturbative analysis of SU(N) Yang-Mills theory in a class of maximal Abelian gauges is presented. We point out the existence of a new nonintegrated renormalizable Ward ide…

F^5 contributions to the nonabelian Born Infeld action from a supersymmetric Yang-Mills five-point function

Andrea Refolli, Alberto Santambrogio, Niccolo' Terzi +1

We consider the N=4 supersymmetric Yang-Mills theory in four dimensions. We compute the one-loop contributions to the effective action with five external vector fields and compare…

Universality and a generalized C-function in CFTs with AdS Duals

D. Klemm, A. C. Petkou, G. Siopsis +1

We argue that the thermodynamics of conformal field theories with AdS duals exhibits a remarkable universality. At strong coupling, a Cardy-Verlinde entropy formula holds even when…

Non(anti)commutative Superspace

Dietmar Klemm, Silvia Penati, Laura Tamassia

We investigate the most general non(anti)commutative geometry in N=1 four-dimensional superspace, invariant under the classical (i.e., undeformed) supertranslation group. We find t…

Exceptional non-renormalization properties and OPE analysis of chiral four-point functions in N=4 SYM_4

G. Arutyunov, B. Eden, A. C. Petkou +1

We show that certain classes of apparently unprotected operators in N=4 SYM_4 do not receive quantum corrections as a consequence of a partial non-renormalization theorem for the 4…

Causality Violation and Naked Time Machines in AdS_5

M. M. Caldarelli, D. Klemm, W. A. Sabra

We study supersymmetric charged rotating black holes in AdS, and show that closed timelike curves occur outside the event horizon. Also upon lifting to rotating D3 brane soluti…

Entropy bounds, monotonicity properties and scaling in CFTs

D. Klemm, A. C. Petkou, G. Siopsis

We study the ratio of the entropy to the total energy in conformal field theories at finite temperature. For the free field realizations of {\cal N}=4 super Yang-Mills theory in D=…
