Supertranslations to all orders
The transformation laws of the general linear superfield V (x, θ, θ) and chiral superfields under N = 1 supertranslations exp[i(ζ ·Q+Q · ζ)] are tabulated to all orders in the parameters ζ , ζ.
متن کاملBMS supertranslations and Weinberg’s soft graviton theorem
Recently it was conjectured that a certain infinite-dimensional “diagonal” subgroup of BMS supertranslations acting on past and future null infinity (I − and I +) is an exact symmetry of the quantum gravity S-matrix, and an associated Ward identity was derived. In this paper we show that this supertranslation Ward identity is precisely equivalent to Weinberg’s soft graviton theorem. Along the w...
متن کاملGravitational memory, BMS supertranslations and soft theorems
The transit of a gravitating radiation pulse past arrays of detectors stationed near future null infinity in the vacuum is considered. It is shown that the relative positions and clock times of the detectors before and after the radiation transit differ by a BMS supertranslation. An explicit expression for the supertranslation in terms of moments of the radiation energy flux is given. The relat...
متن کاملHigher-Dimensional Supertranslations and Weinberg’s Soft Graviton Theorem
Asymptotic symmetries of theories with gravity in d = 2m+2 spacetime dimensions are reconsidered for m > 1 in light of recent results concerning d = 4 BMS symmetries. Weinberg’s soft graviton theorem in 2m + 2 dimensions is re-expressed as a Ward identity for the gravitational S-matrix. The corresponding asymptotic symmetries are identified with 2m + 2-dimensional supertranslations. An alternat...
متن کاملBrs Cohomology of the Supertranslations in D=4
Supersymmetry transformations are a kind of square root of spacetime translations. The corresponding Lie superalgebra always contains the supertranslation operator δ = c α σ µ α ˙ β c ˙ β (ǫ µ) †. We find that the cohomology of this operator depends on a spin-orbit coupling in an SU (2) group and has a quite complicated structure. This spin-orbit type coupling will turn out to be basic in the c...
