Author(s): Lara B. Anderson, Callum R. Brodie, and James Gray The authors study transitions of particular string compactifications (heterotic theories with N=1 supersymmetry in four dimensions) that change the topology and other nonpertubative properties of the internal manifold. This is part of trying to understand the string landscape, here the moduli space of heterotic compactifications, and string effective field theories. The authors provide...

Author(s): Tomasz Krajewski, Marek Lewicki, and Mateusz Zych The authors use numerical lattice simulations to study bubble nucleation in cosmological phase transitions. The terminal bubble velocity is an important parameter for the primordial gravitational wave spectrum as well as for electroweak (EW) baryogenesis. They are able to study an extreme parameter space that is the most promising for these phenomena. However, they find a hydrodynamical...

Author(s): D. Basilico et al. (Borexino Collaboration) Although only one percent or so of the sun’s luminosity comes from the Carbon-Nitrogen-Oxygen (CNO) reaction cycle, the Borexino Collaboration has managed to discriminate neutrinos arising from this process from the dominant pp cycle. In this new study, the collaboration uses a recently developed technique called the “correlated integrated directionality” (CID) method. This is an efficient...

Author(s): J. I. McDonald and S. J. Witte The authors present a “ray-tracing” framework to compute radio emission associated with axion-photon conversion in the vicinity of magnetars. They show that future radio telescopes should be able to explore QCD axion parameter space, independently from a magnetar’s astrophysical model. [Phys. Rev. D 108, 103021] Published Mon Nov 13, 2023

Author(s): Fabrizio Caola, Radosław Grabarczyk, Maxwell L. Hutt, Gavin P. Salam, Ludovic Scyboz, and Jesse Thaler A longstanding goal in collider analysis has been to assign flavor consistently to jets of final state particles which can then be associated with the initial partons coming from hard scattering processes. This paper presents “Interleaved Flavor Neutralization” to define jets with infrared- and collinear-safe (IRC safe) flavor and...

Author(s): Toshiki Kurita and Masahiro Takada 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. [Phys. Rev. D 108, 083533] Published Tue Oct 31, 2023
