Supersymmetric Yang-Mills Theories
Abstract Yang-Mills theories with simple supersymmetry are constructed in 2, 4, 6, and 10 dimensions, and it is argued that these are essentially the only cases possible. The method of dimensional… Expand
N=4 Yang-Mills and N=8 Supergravity as Limits of String Theories
The formulation of supersymmetric string theories in ten dimensions is generalized to incorporate compactified dimensions. Expressions for the one-loop four-particle S -matrix elements of N = 4… Expand
N=4 Yang-Mills Theory on the Light Cone
Abstract The 10-dimensional supersymmetric Yang-Mills theory is constructed in the light-cone gauge. When the theory is dimensionally reduced to four dimensions it is shown that the corresponding N =… Expand

Superfield Theory of Type (ii) Superstrings
Abstract Type (II) superstrings are described by light-cone superfields that are functionals of string superspace coordinates x i ( σ ) and ϑ a ( σ ) or the conjugate momenta p i ( σ ) and λ a ( σ ).… Expand
The $N=8$ Supergravity in Superspace
Abstract The N =8 supergravity is presented in superspace. The theory is on-shell and has the expected local SU(8) and global E 7 invariances.
The Tradeoff between Expected Return and Risk Among Cornbelt Farmers
The inclusion of risk in farm-planning models has been the subject of many theoretical discussions, often with the conclusion that explicit risk consideration features are desirable. Operational… Expand
A Lagrangian formulation of the classical and quantum dynamics of spinning particles
Abstract A spinning particle is described in terms of its position φ μ ( τ ) and of an additional spin degree of freedom ψ μ ( τ ) which is an odd element of a Grassmann algebra. Its motion is… Expand
The ultra-violet finiteness of the N=4 Yang-Mills theory☆
Abstract The N =4 supersymmetric Yang-Mills gauge theory was formulated by us in a previous paper in the light-cone gauge. It is described by a scalar complex superfield whose components are the… Expand
Eleven-dimensional supergravity on the mass shell in superspace
Abstract The eleven-dimensional supergravity theory is presented in superspace on the mass shell.
