Mass/electric versus NUT/magnetic charges: duality from scattering amplitudes in $D\ge 4$ and for all bosonic spins

Ricardo Monteiro, Lecheng Ren, Daniel Siretanu

We revisit Kerr-NUT metrics and related spin-$s$ fields in $D\ge 4$, and study their associated scattering amplitudes. Starting in position space, we highlight the interpretation o…
