Mass/electric versus NUT/magnetic charges: duality from scattering amplitudes in and for all bosonic spins
Ricardo Monteiro, Lecheng Ren, Daniel Siretanu
We revisit Kerr-NUT metrics and related spin- fields in , and study their associated scattering amplitudes. Starting in position space, we highlight the interpretation o…
Memory effect from the scattering of Taub-NUT black holes
George Doran, Ricardo Monteiro, Nathan Moynihan
Taub-NUT black holes are somewhat exotic solutions to the vacuum Einstein equations, which have received limited attention in gravitational phenomenology. We use the soft behaviour…
Superstring amplitudes from the field-theory limit: an n-point map at one loop
Ricardo Monteiro, Lecheng Ren
Are perturbative superstring amplitudes for massless external states just an dressing of super-Yang-Mills/supergravity? This is the case at tree level, where the worldsheet c…
Superstring amplitudes from BCJ numerators at one loop
Yvonne Geyer, Jiachen Guo, Ricardo Monteiro +1
We find a direct map that determines moduli-space integrands for one-loop superstring amplitudes in terms of field-theory loop integrands in the BCJ form. The latter can be compute…
Light-cone actions and correlators of self-dual theories in AdS
Chandramouli Chowdhury, George Doran, Arthur Lipstein +3
Self-dual Yang-Mills and Einstein gravity in Euclidean AdS are useful toy models because they can be described by simple scalar Lagrangians exhibiting a new manifestation of th…
