Matrix reduction and the su(2|2) superalgebra in AdS/CFT
Matrix reduction and the su(2|2) superalgebra in AdS/CFT
We study the supersymmetry generators Q, S on the 1-loop vectorless sector of N=4 Super Yang-Mills, by reduction to the plane-wave matrix model. Using a coherent basis in the su(2|2) sector, a comparison with the algebra given by Beisert in nlin/0610017 is presented, and some parameters (up to one-loop) are determined. We make a final comparison of these supercharges with the results that can be obtained from the string action by working in the light-cone-gauge and discretizing the string.

Abstract
We study the supersymmetry generators Q, S on the 1-loop vectorless sector of N=4 Super Yang-Mills, by reduction to the plane-wave matrix model. Using a coherent basis in the su(2|2) sector, a comparison with the algebra given by Beisert in nlin/0610017 is presented, and some parameters (up to one-loop) are determined. We make a final comparison of these supercharges with the results that can be obtained from the string action by working in the light-cone-gauge and discretizing the string.
