Hudspith and D. Mohler Phys. Rev. D 107, 114510 (2023) – Published 16 June 2023 The authors use six splittings between bottomonium levels to nonperturbatively tune an NRQCD action on four gauge field ensembles. They then use the tuned action for the b antiquarks in their study of the binding energies of exotic tetraquark states with two b antiquarks, achieving a roughly 10% precision in the computed binding energies.     Editors' Suggestion Stochasticity of cosmic rays from supernova remnants and the ionization rates in molecular clouds Vo Hong Minh Phan, Sarah Recchia, Philipp Mertsch, and Stefano Gabici Phys. Rev. D 107, 123006 (2023) – Published 8 June 2023 This paper demonstrates that a stochastic, rather than uniform, injection rate of MeV cosmic rays from supernovae can successfully model the observed ionization rate distribution for Galactic molecular clouds.     Editors' Suggestion Peculiar velocity effects on the Hubble constant from time-delay cosmography Charles Dalang, Martin Millon, and Tessa Baker Phys. Rev. D 107, 123528 (2023) – Published 21 June 2023 The paper studies the determination of the Hubble constant from time delays for a sample of strongly lensed quasars. It focuses on the impact of peculiar velocities and examines a possible relation between the tensions for Hubble constant and CMB dipole measurements.     Editors' Suggestion Stochastic gravitational wave background reconstruction for a nonequilateral and unequal-noise LISA constellation Olaf Hartwig, Marc Lilley, Martina Muratore, and Mauro Pieroni Phys. Rev. D 107, 123531 (2023) – Published 21 June 2023 This paper represents a major step in developing LISA Time Delay Interferometry (TDI) techniques to separate the Stochastic Gravitational Wave Signal from instrumental noise, and shows how different TDI variables can be critical in this respect.     Editors' Suggestion Bridging Carrollian and celestial holography Laura Donnay, Adrien Fiorucci, Yannick Herfray, and Romain Ruzziconi Phys. Rev. D 107, 126027 (2023) – Published 30 June 2023 Formulating a precise notion of holography between gravity in asymptotically flat spacetime and a lower-dimensional field theory remains an outstanding problem. In this paper, the authors discuss two seemingly disparate existing approaches to such a duality, namely the celestial and Carrolian holography, and show that they are connected by an integral transform.       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.
