Symmetries of the Celestial Supersphere

A Tropper - arXiv preprint arXiv:2412.13113, 2024 - arxiv.org
We study the celestial CFT dual to theories with bulk supersymmetry. The boundary theory
realizes supersymmetry in the spirit of the Green-Schwarz superstring: there is manifest 4d …

algebra and the dual theory of 3D asymptotically flat higher spin gravity

N Banerjee, A Bhattacharjee, S Biswas, A Mitra… - Physical Review D, 2024 - APS
Bondi-Metzner-Sachs (BMS) algebra in three spacetime dimensions can be deformed into a
two parameter family of algebra known as W (a, b) algebra. For a= 0, we show that other …

Asymptotic symmetry algebra of supergravity

N Banerjee, T Rahnuma, RK Singh - Physical Review D, 2024 - APS
The asymptotic symmetry algebra of N= 1 supergravity was recently constructed using the
well-known two-dimensional celestial conformal field (CFT) theory technique [A. Fotopoulos …

Soft and collinear limits in = 8 supergravity using double copy formalism

N Banerjee, T Rahnuma, RK Singh - Journal of High Energy Physics, 2023 - Springer
A bstract It is known that 𝒩= 8 supergravity is dual to 𝒩= 4 super Yang-Mills (SYM) via the
double copy relation. Using the explicit relation between scattering amplitudes in the two …

Quantum flux operators in the fermionic theory and their supersymmetric extension

SM Guo, WB Liu, J Long - arXiv preprint arXiv:2412.20829, 2024 - arxiv.org
We construct quantum flux operators with respect to the Poincar\'e symmetry in the massless
Dirac theory at future null infinity. An anomalous helicity flux operator emerges from the …

Supersymmetric Soft Theorems

A Tropper - arXiv preprint arXiv:2404.03717, 2024 - arxiv.org
We show that in supersymmetric theories, knowing the soft theorem for a single particle in a
supermultiplet allows one to immediately determine soft theorems for the remainder of the …
