The SU(2|3) Spin Chain Sigma Model
The one-loop planar dilatation operator of N = 4 supersymmetric Yang-Mills is isomorphic to the hamiltonian of an integrable PSU(2; 2|4) spin chain. We construct the non-linear sigma model describing the continuum limit of the SU(2|3) subsector of the N = 4 chain. We explicitly identify the spin cha...

| Sumario: | The one-loop planar dilatation operator of N = 4 supersymmetric Yang-Mills is isomorphic to the hamiltonian of an integrable PSU(2; 2|4) spin chain. We construct the non-linear sigma model describing the continuum limit of the SU(2|3) subsector of the N = 4 chain. We explicitly identify the spin chain sigma model with the one for a superstring moving in AdS5 x S5 with large angular momentum along the ve-sphere. |
