AdS S-Matrix for Massive Vector Fields

Nabamita Banerjee, Amogh Neelkanth Desai, Karan Fernandes +2

We generalize a recent ``AdS S-matrix" formulation for interacting massive scalars on AdS spacetimes to the case of massive vector fields. This method relies on taking the infinite…

Soft factors with AdS radius corrections

Karan Fernandes, Nabamita Banerjee, Arpita Mitra

We review recent developments concerning the soft factorization of scattering amplitudes that arise in the large radius limit of four dimensional Anti-de Sitter (AdS) spacetime…

Celestial Eikonal Amplitudes in the Near-Horizon Region

Karan Fernandes, Feng-Li Lin, Arpita Mitra

We investigate the celestial description of an eikonal amplitude for the scattering of massless scalars mediated by soft gravitons in the near-horizon region of a large eternal Sch…

corrected soft photon theorem from a CFT Ward identity

Nabamita Banerjee, Karan Fernandes, Arpita Mitra

Classical soft theorems applied to probe scattering processes on AdS spacetimes predict the existence of corrections to the soft photon and soft graviton factors of asy…

Soft Photon theorem in the small negative cosmological constant limit

Nabamita Banerjee, Karan Fernandes, Arpita Mitra

We study the effect of electromagnetic interactions on the classical soft theorems on an asymptotically AdS background in 4 spacetime dimensions, in the limit of a small cosmologic…

Horizon Hair from Inversion Symmetry

Karan Fernandes, Debodirna Ghosh, Amitabh Virmani

The extreme Reissner-Nordström solution has a discrete conformal isometry that maps the future event horizon to future null infinity and vice versa, the Couch-Torrence inversion is…
