Abstract

Neutrinos are neutral in the Standard Model, but they have tiny charge radii generated by radiative corrections. In theories beyond the Standard Model, neutrinos can also have magnetic and electric moments and small electric charges (millicharges). We review the general theory of neutrino electromagnetic form factors, which reduce, for ultrarelativistic neutrinos and small momentum transfers, to the neutrino charges, effective charge radii, and effective magnetic moments. We discuss the phenomenology of these electromagnetic neutrino properties and review the existing experimental bounds. We also briefly review the electromagnetic processes of astrophysical neutrinos and the neutrino magnetic moment portal in the presence of sterile neutrinos.

中微子电磁特性

在标准模型中，中微子是中性的，但它们有很小的由辐射修正产生的电荷半径。在标准模型之外的理论中，中微子也可以具有磁矩和电矩以及小电荷（毫荷）。我们回顾了中微子电磁形状因子的一般理论，对于超相对论性中微子和小动量转移，它们减少到中微子电荷，有效电荷半径和有效磁矩。我们讨论了这些电磁中微子性质的现象学，并回顾了现有的实验边界。我们还简要回顾了天体物理中微子的电磁过程和中微子在惰性中微子存在下的磁矩门户。

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.
