Amhis et al. (Heavy Flavor Averaging Group Collaboration) Phys. Rev. D 107, 052008 (2023) – Published 23 March 2023 Synopsis:Heavy-Flavor Properties Get an Update The Heavy Flavor Averaging Group has released new world averages for properties of "heavy-flavor" particle decays—an update aimed at improving our understanding of flavor physics.     Featured in Physics Editors' Suggestion Prototype global analysis of LISA data with multiple source types Tyson B. Littenberg and Neil J. Cornish Phys. Rev. D 107, 063004 (2023) – Published 7 March 2023 Synopsis:Analyzing the Gravitational-Wave Sky A space-based observatory will detect gravitational waves from so many different types of sources at once that a global approach will be needed to crunch the data.     Editors' Suggestion Anisotropic photon and electron scattering without ultrarelativistic approximation Anderson C. M. Lai and Kenny C. Y. Ng Phys. Rev. D 107, 063026 (2023) – Published 24 March 2023 The authors present exact numerical computations leading to a general theoretical formalism of Compton and inverse Compton scattering in several key astrophysical processes, such as X- γ-ray polarization and astrophysical jets. Their assumption of (1) anisotropic photons and electrons, and (2) no ultrarelativistic approximations, demonstrates major deviations in certain regimes compared to previous calculations.     Editors' Suggestion Perturbation theory with dispersion and higher cumulants: Framework and linear theory Mathias Garny, Dominik Laxhuber, and Román Scoccimarro Phys. Rev. D 107, 063539 (2023) – Published 24 March 2023 The authors develop an alternative perturbative approach to gravitational clustering and the large-scale structure. This approach is complementary to the effective field theory approach while being much more predictive and providing a more detailed understanding of mechanisms like the decoupling of nonlinear small-scale modes into dark matter halos where standard perturbation theory completely fails. This is an exciting step into the future of making predictions, especially in light of upcoming Stage IV experiments.     Editors' Suggestion Perturbation theory with dispersion and higher cumulants: Nonlinear regime Mathias Garny, Dominik Laxhuber, and Román Scoccimarro Phys.

Green, Stefan Hollands, Laura Sberna, Vahid Toomani, and Peter Zimmerman Phys. Rev. D 107, 064030 (2023) – Published 13 March 2023 Using a symmetry of the Kerr spacetime, the authors determine an original bilinear form for perturbations of the Weyl scalars. They show that upon choosing appropriate integration contours, this form can also be used on quasi-normal mode data. This manuscript provides a formalism for studying ringdown beyond the leading order, with potential application to numerical relativity and gravitational wave observation.     Editors' Suggestion Binary geometries, generalized particles and strings, and cluster algebras Nima Arkani-Hamed, Song He, Thomas Lam, and Hugh Thomas Phys. Rev. D 107, 066015 (2023) – Published 17 March 2023 The authors study the fundamental properties of scattering amplitudes of particles in any spacetime dimension. They introduce binary geometries, giving a completely rigid geometric realization of the combinatorics of generalized associahedra attached to any Dynkin diagram. Furthermore, they define open and closed "cluster string integrals", which provide a generalization of particle and string scattering amplitudes, and enjoy remarkable factorization properties at finite α′.     American Physical Society: 1 Physics Ellipse, College Park, MD 20740 ©2023 American Physical Society | All rights reserved You are receiving this email because you are subscribed to Table of Content alerts.
