Rev. D 106, 093006 (2022) – Published 21 November 2022 | Neutrino beam experiments to measure neutrino cross sections on nuclear targets are part of a major experimental program. In this paper, the authors compute radiative QED corrections to neutrino-nucleus scattering using effective field theory methods that separate perturbative QED soft and collinear contributions from hard nuclear ones. Applications of this framework are promising because theoretical control of neutrino-nucleus scattering is crucial to making sense of experimental data. | | | | | | Editors' Suggestion Rodrigo Fernández, Sherwood Richers, Nicole Mulyk, and Steven Fahlman Phys. Rev. D 106, 103003 (2022) – Published 3 November 2022 | Neutron star mergers are of tremendous astrophysical interest for a variety of reasons that include their role in initiating r-process nucleosynthesis in their ejecta. In this article, the authors tackle the complex influence of extremely rapid neutrino flavor conversion (fast flavor instability - FFI) on ejecta from accretion disks around hypermassive neutron stars (HMNSs) formed in mergers. By studying a wide variety of scenarios, the authors detail the influence of FFI and show that it depends strongly on the lifetime of the HMNS. | | | | | | Editors' Suggestion Marek Lewicki, Ville Vaskonen, and Hardi Veermäe Phys. Rev. D 106, 103501 (2022) – Published 3 November 2022 | The authors set up a new method (proof of concept) for studying bubble wall dynamics in first-order cosmological phase transitions based on N-body simulations. The technique goes beyond commonly used perfect fluid descriptions and equilibrium assumptions. This allows e.g. the computation of the terminal bubble wall velocity, a key ingredient for determining the gravitational wave signal created in the cosmological phase transition, based on particle physics properties rather than on phenomenological fluid parameters. | | | | | | Featured in Physics Editors' Suggestion David Ellis, David J. E. Marsh, Benedikt Eggemeier, Jens Niemeyer, Javier Redondo, and Klaus Dolag Phys. Rev. D 106, 103514 (2022) – Published 15 November 2022 | Asteroid-sized clumps of a dark matter candidate known as an axion could be detectable in a gravitational-microlensing survey. | | | | | | Editors' Suggestion Mohammed Khalil, Raissa F. P. Mendes, Néstor Ortiz, and Jan Steinhoff Phys. Rev. D 106, 104016 (2022) – Published 9 November 2022 | The authors provide a model for dynamical scalarization, beyond the adiabatic approximation, using effective field theory techniques, demonstrating that the inclusion of post-adiabatic corrections is crucial. The model is agnostic, i.e., independent of a specific theory of gravity and can therefore be used even for alternative gravity theories. | | | | | | Featured in Physics Valentin Deliyski, Galin Gyulchev, Petya Nedkova, and Stoytcho Yazadjiev Phys. Rev. D 106, 104024 (2022) – Published 10 November 2022 | Predictions indicate that wormholes and black holes may have nearly identical polarized light spectra, making these astrophysical objects difficult to distinguish. | | | | | | Editors' Suggestion Tousif Islam, Scott E. Field, Scott A. Hughes, Gaurav Khanna, Vijay Varma, Matthew Giesler, Mark A. Scheel, Lawrence E. Kidder, and Harald P. Pfeiffer Phys. Rev. D 106, 104025 (2022) – Published 14 November 2022 | Gravitational waveforms obtained using numerical relativity (NR) are computationally expensive and slow. Surrogate models provide an alternative to full NR by extrapolating from the point-particle regime of high-mass ratio binary waveforms calibrated to NR to much smaller mass ratios. The authors show that their methods work over a remarkable range of mass ratios of 2.5 to 10000 showing good agreement with NR simulations. | | | | | | Editors' Suggestion Bernardo Porto Veronese and Carsten Gundlach Phys. Rev. D 106, 104044 (2022) – Published 22 November 2022 | The authors numerically study the interactions between scalar fields and gravitational waves in the context of gravitational collapse at the threshold of black hole formation in 4+1 dimensions. They find evidence for the existence of a co-dimension two attractor in the dynamical systems picture. | | | | | | Editors' Suggestion Chiung Hwang, Sara Pasquetti, and Matteo Sacchi Phys. Rev. D 106, 105014 (2022) – Published 17 November 2022 | The authors develop an algorithm for a field theoretical implementation of mirror symmetry. This is based on the so-called quiver representation of certain N=1 supersymmetric theories and is a non-abelian generalization of the piecewise dualization of three-dimensional abelian theories. Extensions of this local field-theoretic operations to non-supersymmetric theories are expected. | | | | | | Editors' Suggestion Tyler Gorda, Juuso Österman, and Saga Säppi Phys. Rev. D 106, 105026 (2022) – Published 29 November 2022 | Within the framework of the imaginary time formalism applied to systems at zero temperature but finite density, the authors investigate whether the order of integration, namely the spatial momentum integration is performed before that of the temporal momentum or vice versa, matters. They show that the former yields results consistent with those for nonzero but very low values of the temperature whilst the latter does not. They attribute this to the way the limit of the Fermi-Dirac distribution is taken as the temperature goes to zero. | | | | | | | |
