On the spectrum of AdS/CFT beyond supergravity
N. Beisert, M. Bianchi, J. F. Morales +1
We test the spectrum of string theory on AdS_5 x S^5 derived in hep-th/0305052 against that of single-trace gauge invariant operators in free N=4 super Yang-Mills theory. Masses of…
The su(2|3) Dynamic Spin Chain
Niklas Beisert
The complete one-loop, planar dilatation operator of the N=4 superconformal gauge theory was recently derived and shown to be integrable. Here, we present further compelling eviden…
Precision Spectroscopy of AdS/CFT
N. Beisert, S. Frolov, M. Staudacher +1
We extend recent remarkable progress in the comparison of the dynamical energy spectrum of rotating closed strings in AdS_5xS^5 and the scaling weights of the corresponding non-nea…
Higher loops, integrability and the near BMN limit
Niklas Beisert
In this note we consider higher-loop contributions to the planar dilatation operator of N=4 SYM in the su(2) subsector of two complex scalar fields. We investigate the constraints…
The N=4 SYM Integrable Super Spin Chain
Niklas Beisert, Matthias Staudacher
Recently it was established that the one-loop planar dilatation generator of N=4 Super Yang-Mills theory may be identified, in some restricted cases, with the Hamiltonians of vario…
The Complete One-Loop Dilatation Operator of N=4 Super Yang-Mills Theory
Niklas Beisert
We continue the analysis of hep-th/0303060 in the one-loop sector and present the complete psu(2,2|4) dilatation operator of N=4 Super Yang-Mills theory. This operator generates th…
Stringing Spins and Spinning Strings
N. Beisert, J. A. Minahan, M. Staudacher +1
We apply recently developed integrable spin chain and dilatation operator techniques in order to compute the planar one-loop anomalous dimensions for certain operators containing a…
The Dilatation Operator of Conformal N=4 Super Yang-Mills Theory
N. Beisert, C. Kristjansen, M. Staudacher
We argue that existing methods for the perturbative computation of anomalous dimensions and the disentanglement of mixing in N = 4 gauge theory can be considerably simplified, syst…
