Constraints on a Massive Double-Copy and Applications to Massive Gravity
Laura A. Johnson, Callum R. T. Jones, Shruti Paranjape
We propose and study a BCJ double-copy of massive particles, showing that it is equivalent to a KLT formula with a kernel given by the inverse of a matrix of massive bi-adjoint sca…

All-Multiplicity One-Loop Amplitudes in Born-Infeld Electrodynamics from Generalized Unitarity
Henriette Elvang, Marios Hadjiantonis, Callum R. T. Jones +1
We initiate a study of non-supersymmetric Born-Infeld electrodynamics in 4d at the quantum level. Explicit all-multiplicity expressions are calculated for the purely rational one-l…

Soft Bootstrap and Supersymmetry
Henriette Elvang, Marios Hadjiantonis, Callum R. T. Jones +1
The soft bootstrap is an on-shell method to constrain the landscape of effective field theories (EFTs) of massless particles via the consistency of the low-energy S-matrix. Given a…
