Next-to-soft radiation from a different angle
(American Physical Society, 2024-04-08)Soft and collinear radiation in collider processes can be described in a universal way, that is independent of the underlying process. Recent years have seen a number of approaches for probing whether radiation beyond the ... -
No U(1) ‘electric-magnetic’ duality in Einstein gravity
(Springer Nature, 2024-04-17)We revisit the question of whether classical general relativity obeys, beyond the linearised order, an analogue of the global U(1) electric-magnetic duality of Maxwell theory, with the Riemann tensor playing the role ... -
Non-Abelian supertubes

Non-Perturbative Explorations of Chiral Rings in 4d N=2 SCFTs
(American Physical Society, 2023)We study the conditions under which 4d N = 2 superconformal field theories (SCFTs) have multiplets housing operators that are chiral with respect to an N = 1 subalgebra. Our main focus is on the set of often-ignored and ... -

Orbital precession and hidden symmetries in scalar-tensor theories
(IOP Publishing, 2023-11-01)We revisit the connection between relativistic orbital precession, the Laplace-Runge-Lenz symmetry, and the t-channel discontinuity of scattering amplitudes. Applying this to scalar-tensor theories of gravity, we compute ... -
Pions as gluons in higher dimensions

Positivity and the electroweak hierarchy
(American Physical Society, 2024-02-21)We point out that an unnatural hierarchy between certain higher-dimensional operator coefficients in a low-energy effective field theory (EFT) would automatically imply that the Higgs' vacuum expectation value is hierarchically ...
