Abstract

Solid-state phonon and charge detectors probe the scattering of weakly interacting particles, such as dark matter and neutrinos, through their low recoil thresholds. Recent advancements have pushed sensitivity to eV-scale energy depositions, uncovering previously unseen low-energy excess backgrounds. While some arise from known processes such as thermal radiation, luminescence, and stress, others remain unexplained. This review examines these backgrounds, their possible origins, and parallels to low-energy effects in solids, an understanding of which is essential for interpreting particle interactions at and below the eV scale.

固体声子和电荷探测器中的低能量背景

固体声子和电荷探测器探测弱相互作用粒子的散射，如暗物质和中微子，通过它们的低反冲阈值。最近的进展提高了对电动汽车规模能量沉积的敏感性，发现了以前未见过的低能量过剩背景。虽然有些是由已知的过程引起的，如热辐射、发光和应力，但其他的仍然无法解释。这篇综述考察了这些背景，它们可能的起源，以及与固体中低能量效应的相似之处，理解这些对于解释eV尺度和eV尺度以下的粒子相互作用至关重要。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
