Search for non-virialized axions with 3.3-4.2 $μ$eV mass at selected resolving powers

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: A. T. Hipp, A. Quiskamp, T. J. Caligiure, J. R. Gleason, Y. Han | Summary: The Axion Dark Matter eXperiment is sensitive to narrow axion flows, given axions compose a fraction of the dark matter with a non-negligible local density. Detecting these low-velocity dispersion flows requires a […]

Gravitational Effects of Null Particles

Kavli Affiliate: Craig Hogan | First 5 Authors: Kris Mackewicz, Craig Hogan, , , | Summary: We generalize earlier solutions of gravitational shocks sourced by distributional null stress-energy and analyze their observable effects. A systematic method is proposed to demonstrate consistency between the gravitational effects of a null perfect fluid, i.e. a photon gas, and […]

Measuring the Inconsistency of Large Language Models in Preferential Ranking

Kavli Affiliate: Ke Wang | First 5 Authors: Xiutian Zhao, Ke Wang, Wei Peng, , | Summary: Despite large language models’ (LLMs) recent advancements, their bias and hallucination issues persist, and their ability to offer consistent preferential rankings remains underexplored. This study investigates the capacity of LLMs to provide consistent ordinal preferences, a crucial aspect […]

The spin lifetime of an individual atomic nucleus investigated via local-probe single-shot readout

Kavli Affiliate: Sander Otte | First 5 Authors: Evert W. Stolte, Jinwon Lee, Hester Vennema, Rik Broekhoven, Esther Teng | Summary: Nuclear spins owe their long-lived magnetic states to their excellent isolation from their environment. At the same time, a limited degree of interaction with their surroundings is necessary for reading and writing the spin […]

Observation of time-dependent $CP$ violation and measurement of the branching fraction of $B^0 to J/ψπ^0$ decays

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, H. Aihara | Summary: We present a measurement of the branching fraction and time-dependent charge-parity ($CP$) decay-rate asymmetries in $B^0 to J/psi pi^0$ decays. The data sample was collected with the Belle~II detector at the SuperKEKB asymmetric $e^+e^-$ […]
