Rev. D 108, 074015 (2023) – Published 19 October 2023 A theoretical study demonstrates that in-medium showers of high-energy gluons can be approximately treated as a sequence of individual splitting processes.     Editors' Suggestion Inclusive hadronic decay rate of the τ lepton from lattice QCD A. Evangelista, R. Frezzotti, N. Tantalo, G. Gagliardi, F. Sanfilippo, S. Simula, and V. Lubicz (Extended Twisted Mass Collaboration) Phys. Rev. D 108, 074513 (2023) – Published 19 October 2023 The authors express the inclusive hadronic decay rate of the tau lepton as an integral over the spectral density of the two-point correlator of the weak V−A hadronic current which they compute fully nonperturbatively in lattice QCD. In a lattice QCD computation with all systematic errors except for isospin breaking effects under control, they then obtain the CKM matrix element Vud with subpercent errors showing that their nonperturbative method can become a viable alternative to superallowed nuclear beta decays for obtaining Vud.     Editors' Suggestion Characterizing cosmic birefringence in the presence of Galactic foregrounds and instrumental systematic effects Baptiste Jost, Josquin Errard, and Radek Stompor Phys. Rev. D 108, 082005 (2023) – Published 19 October 2023 The authors propose a new analysis framework to account simultaneously for Galactic foregrounds and instrumental effects, in order to break the degeneracy between Cosmic Birefringence (CB) angle and Cosmic Microwave Background detector effects. They thus pave the way for Simons Observatory-like Small Aperture Telescopes to test claims for CB detection.     Editors' Suggestion Simple parameter estimation using observable features of gravitational-wave signals Stephen Fairhurst, Charlie Hoy, Rhys Green, Cameron Mills, and Samantha A. Usman Phys. Rev. D 108, 082006 (2023) – Published 23 October 2023 Rapid extraction of parameters to characterize sources of gravitational wave signals is vitally important to gravitational wave astronomy. This paper provides an intuitive method for extracting parameters more efficiently than existing full parameter estimation methods. Among other applications, these new methods appear to be promising ways of addressing real-time needs such as generating gravitational wave event alerts.     Editors' Suggestion Constraints on anisotropic primordial non-Gaussianity from intrinsic alignments of SDSS-III BOSS galaxies Toshiki Kurita and Masahiro Takada Phys. Rev. D 108, 083533 (2023) – Published 31 October 2023 The authors employ a novel power-spectrum estimator to measure galaxy intrinsic alignments from Sloan Digital Sky Survey data. They showcase the method's usefulness, constraining the level of non-gaussianities in primordial cosmological structure perturbations.     Editors' Suggestion Causal connectability between quantum systems and the black hole interior in holographic duality Samuel Leutheusser and Hong Liu Phys. Rev. D 108, 086019 (2023) – Published 12 October 2023 In a series of two papers, the authors explore the holographic duality between an eternal AdS black hole in the bulk and two copies of the boundary CFT in the thermal field double state. They provide an explicit construction in the boundary theory of an evolution operator for a bulk in-falling observer, thus making manifest the boundary emergence of the black hole horizons, the interiors, and the associated causal structure. They also elucidate that the emergence of the sharp bulk event horizon is related to the infinite N limit of the boundary theory.     Editors' Suggestion Emergent times in holographic duality Sam Leutheusser and Hong Liu Phys. Rev. D 108, 086020 (2023) – Published 12 October 2023 In a series of two papers, the authors explore the holographic duality between an eternal AdS black hole in the bulk and two copies of the boundary CFT in the thermal field double state. They provide an explicit construction in the boundary theory of an evolution operator for a bulk in-falling observer, thus making manifest the boundary emergence of the black hole horizons, the interiors, and the associated causal structure.
