String corrections to AdS amplitudes and the double-trace spectrum of N=4 SYM

J. M. Drummond, D. Nandan, H. Paul +1

We consider corrections to four-point correlators of half-BPS operators in super Yang-Mills theory in the supergravity limit. By demanding the correct behaviou…

Celestial Amplitudes: Conformal Partial Waves and Soft Limits

Dhritiman Nandan, Anders Schreiber, Anastasia Volovich +1

Massless scattering amplitudes in four-dimensional Minkowski spacetime can be Mellin transformed to correlation functions on the celestial sphere at null infinity called celestial…

All rational one-loop Einstein-Yang-Mills amplitudes at four points

Dhritiman Nandan, Jan Plefka, Gabriele Travaglini

All four-point mixed gluon-graviton amplitudes in pure Einstein-Yang-Mills theory with at most one state of negative helicity are computed at one-loop order and maximal powers of t…

A note on NMHV form factors from the Graßmannian and the twistor string

David Meidinger, Dhritiman Nandan, Brenda Penante +1

In this note we investigate Graßmannian formulas for form factors of the chiral part of the stress-tensor multiplet in superconformal Yang-Mills theory. We present…

Multi-Soft gluon limits and extended current algebras at null-infinity

Tristan McLoughlin, Dhritiman Nandan

In this note we consider aspects of the current algebra interpretation of multi-soft limits of tree-level gluon scattering amplitudes in four dimensions. Building on the relation b…

Collinear limits beyond the leading order from the scattering equations

Dhritiman Nandan, Jan Plefka, Wadim Wormsbecher

The structure of tree-level scattering amplitudes for collinear massless bosons is studied beyond their leading splitting function behavior. These near-collinear limits at sub-lead…
