An analytic superfield formalism for tree superamplitudes in D=10 and D=11
Tree amplitudes of 10D supersymmetric Yang-Mills theory (SYM) and 11D supergravity (SUGRA) are collected in multi-particle counterparts of analytic on-shell superfields which have essentially the same form as their chiral 4D counterparts describing N = 4 SYM and N = 8 SUGRA, but with components dependent on a different set of bosonic variables. These are the D=10 and D=11 spinor helicity variab...

متن کاملSolution to the Ward Identities for Superamplitudes
Supersymmetry and R-symmetry Ward identities relate on-shell amplitudes in a supersymmetric field theory. We solve these Ward identities for NMHV amplitudes of the maximally supersymmetric N = 4 and N = 8 theories. The resulting superamplitude is written in a new, manifestly supersymmetric and R-invariant form: it is expressed as a sum of very simple SUSY and SU(N )R-invariant Grassmann polynom...
متن کاملSUSY Ward identities, Superamplitudes, and Counterterms
Ward identities of SUSY and R-symmetry relate n-point amplitudes in supersymmetric theories. We review recent work in which these Ward identities are solved in N = 4 SYM and N = 8 supergravity. The solution, valid at both tree and loop level, expresses any NMHV superamplitude in terms of a basis of ordinary amplitudes. Basis amplitudes are classified by semi-standard tableaux of rectangular N -...
متن کاملKilling Spinors and SYM on Curved Spaces
Motivated by discussions of wrapped branes in the AdS/CFT context, we investigate globally supersymmetric counterparts of standard Poincaré supersymmetric SYM theories on curved space-times admitting Killing spinors and find two families of theories in all dimensions less than six and eight respectively. The former differs from the standard theory only by mass terms for the fermions and scalars...
