Dynamical supersymmetry in maximally supersymmetric gauge theories

Understand

Maximally supersymmetric theories can be described by a single scalar superfield in light-cone superspace.

• When they are also (super)conformally invariant, they are uniquely specified by the form of the dynamical supersymmetry.
• We present an explicit derivation of the light-cone superspace form of the dynamical supersymmetry in the cases of ten- and four-dimensional super-Yang-Mills, and the three-dimensional Bagger-Lambert-Gustavsson theory, starting from the covariant formulation of these theories.
