# On supersymmetry and other properties of a class of marginally deformed backgrounds

@article{Hernndez2006OnSA, title={On supersymmetry and other properties of a class of marginally deformed backgrounds}, author={R. Hern{\'a}ndez and K. Sfetsos and Dimitrios Zoakos}, journal={Protein Science}, year={2006}, volume={54}, pages={407-415} }

We summarize our recent work on supergravity backgrounds dual to part of the Coulomb branch of N = 1 theories constructed as marginal deformations of N = 4 Yang–Mills. In particular, we present a summary of the behaviour of the heavy quark-antiquark potential which shows confining behaviour in the IR as well as of the spectrum of the wave equation. The reduced supersymmetry is due to the implementation of T-duality in the construction of the deformed supergravity solutions. As a new result we… Expand
