Article Synopsis
- The article presents a new gravitational Compton amplitude for rotating Kerr black holes applicable to any quantum spin, from zero to infinity.
- It utilizes concepts from higher-spin quantum field theory, such as gauge invariance, to derive classical amplitudes with respect to the spin vector.
- The study emphasizes using a chiral-field approach for clarity in degrees of freedom and simplifies interactions, allowing for comparisons with existing general-relativity results up to eighth order in spin.
Article Synopsis
- The dynamics of Kerr black holes are significantly influenced by gauge symmetry principles, leading to the development of effective field theories for these black holes based on integer quantum spins.
- Using Stückelberg fields, the research predicts known three-point Kerr amplitudes through the lens of massive higher-spin gauge symmetry, which may enhance the theories' applicability.
- The study also investigates the root-Kerr electromagnetic solution and examines the interactions with photons, focusing on spin-s Compton amplitudes and the implications of Ward identities for contact-term constraints at spin 2.
This study aimed to investigate the visual biofeedback effect of a sensorized system for plantar pressure dynamic evaluation of in patients with a total hip replacement. Experimental group followed the rehabilitation training wearing sensorized insoles that provided images on three monitors. The control group followed the verbal instructions of physiotherapists during training.

In this Letter, we initiate the study of double copy constructions for these supergravities. We argue that, on general grounds, we expect their scattering amplitudes to be described by a double copy of the type (spontaneously broken gauge theory)⊗ (gauge theory with broken supersymmetry).

The left-hand copy is N=2 super-Yang-Mills theory coupled to a hypermultiplet, whereas the right-hand copy is a nonsupersymmetric theory that can be identified as the dimensional reduction of a D-dimensional Yang-Mills theory coupled to P fermions. For generic D and P, the double copy gives homogeneous supergravities.
