Gauge-string duality for superconformal deformations of N=4 Super Yang-Mills theory

We analyze in detail the relation between an exactly marginal deformation of N = 4 SYM - the Leigh-Strassler or "beta-deformation" - and its string theory dual ( recently constructed in hep-th/0502086) by comparing energies of semiclassical strings to anomalous dimensions of gauge-theory operators in the two-scalar sector. We stress the e...更多
