• ### Direct $CP$ violation and the $\mathrm{Δ}I=1/2$ rule in $K→ππ$ decay from the standard model

Author(s): R. Abbott, T. Blum, P. A. Boyle, M. Bruno, N. H. Christ, D. Hoying, C. Jung, C. Kelly, C. Lehner, R. D. Mawhinney, D. J. Murphy, C. T. Sachrajda, A. Soni, M. Tomii, and T. Wang (RBC and UKQCD Collaborations) A rigorous calculation of a matter-antimatter asymmetry in kaon decays has twice the precision of a previous calculation, removing tension that had existed between theory and experiment. [Phys. Rev. D 102, 054509] Published Thu...
• ### Measurement of the cosmic-ray energy spectrum above $2.5×{10}^{18}\text{ }\text{ }\mathrm{eV}$ using the Pierre Auger Observatory

Author(s): A. Aab et al. (The Pierre Auger Collaboration) New results from the Pierre Auger Observatory could narrow down the search for the origin of ultrahigh-energy cosmic rays. [Phys. Rev. D 102, 062005] Published Wed Sep 16, 2020
• ### Searching for cosmological gravitational-wave backgrounds with third-generation detectors in the presence of an astrophysical foreground

Author(s): Ashish Sharma and Jan Harms Third-generation gravitational-wave detectors, such as the Einstein Telescope and the Cosmic Explorer, are projected to be not only extremely sensitive instruments for detecting compact binary coalescences but also the cosmological gravitational-wave background. However, in order to delineate the stochastic cosmological gravitational-wave background in the observed data, the astrophysical foreground needs...
• ### GW190412: Observation of a binary-black-hole coalescence with asymmetric masses

Author(s): R. Abbott et al. (LIGO Scientific Collaboration and Virgo Collaboration) The merger of two black holes with significantly different masses allows researchers to better characterize black hole parameters and to perform new tests of general relativity. [Phys. Rev. D 102, 043015] Published Mon Aug 24, 2020
• ### Energy trapped Ising model

Author(s): Andrea Amoretti, Gianluca Costagliola, Nicodemo Magnoli, and Marcello Scanavino The authors explore a method for computing correlation functions that is complementary to the well-known bootstrap program and particularly well suited for determining the behavior of off-critical systems, i.e. systems perturbed around their conformal point. They do so for a class of perturbations of the 3D Ising model which are relevant for real experiments...
• ### Early dark energy does not restore cosmological concordance

Author(s): J. Colin Hill, Evan McDonough, Michael W. Toomey, and Stephon Alexander The authors provide a thorough study of a popular scenario (early dark energy EDE) to alleviate the tension in the measurements of the Hubble constant H0, which either rely on early Universe probes and the cosmological standard model (ΛCDM) or on late Universe probes through direct, local distant measurements. The authors show that the inclusion of numerous large...
• ### Transport and hydrodynamics in the chiral limit

Author(s): Eduardo Grossi, Alexander Soloviev, Derek Teaney, and Fanglida Yan For a thermal system with light pions, over large distances both hydrodynamic and chiral modes must be included. The authors accomplish this, and compute the leading corrections in the pion mass squared to transport coefficients. This illuminates the properties of the QCD medium at temperatures close to but below Tc. [Phys. Rev. D 102, 014042] Published Mon Jul 27...
