Mesons in marginally deformed AdS/CFT
Silvia Penati, Marco Pirrone, CarloAlberto Ratti
We study the embedding of spacetime filling D7-branes in beta-deformed backgrounds which, according to the AdS/CFT dictionary, corresponds to flavoring beta-deformed N=4 super Yang…
On the perturbative chiral ring for marginally deformed N=4 SYM theories
Andrea Mauri, Silvia Penati, Marco Pirrone +2
For \cal{N}=1 SU(N) SYM theories obtained as marginal deformations of the \cal{N}=4 parent theory we study perturbatively some sectors of the chiral ring in the weak coupling regim…
Non-protected operators in N=4 SYM and multiparticle states of AdS_5 SUGRA
G. Arutyunov, S. Penati, A. C. Petkou +2
We study a class of non-protected local composite operators which occur in the R symmetry singlet channel of the OPE of two stress-tensor multiplets in {\cal N}=4 SYM. At tree leve…
Supersymmetric Gauge Anomaly with General Homotopic Paths
S. J. Gates, M. T. Grisaru, M. E. Knutt +2
We use the method of Banerjee, Banerjee and Mitra and minimal homotopy paths to compute the consistent gauge anomaly for several superspace models of SSYM coupled to matter. We rev…
A Quantum Field Theory with Infinite Resonance States
G. Mussardo, S. Penati
We study an integrable quantum field theory of a single stable particle with an infinite number of resonance states. The exact --matrix of the model is expressed in terms of Jac…
Gravitational Dressing of N=2 Sigma-Models Beyond Leading Order
S. Penati, A. Santambrogio, D. Zanon
We study the beta-function of the N=2 sigma-model coupled to N=2 induced supergravity. We compute corrections to first order in the semiclassical limit, , beyond one…
