摘要

在弹性中微子-核子散射的理论表述中，对大质量狄拉克中微子的电磁相互作用及其自旋风味态进行了详尽的描述。在三中微子混合的假设下，将中微子电荷、磁、电和拟极点形式因子定义为质量基中的矩阵。以到达探测器的中微子的自旋-风味密度矩阵的形式考虑了从源传播到探测器的中微子的风味和自旋变化。概述了中微子电荷半径、磁矩和自旋极化对中微子-核子散射实验的潜在影响。2025年由美国物理学会出版

Electromagnetic interactions in elastic neutrino-nucleon scattering

A thorough account of electromagnetic interactions of massive Dirac neutrinos as well as their spin-flavor state in the theoretical formulation of elastic neutrino-nucleon scattering is given. The formalism of neutrino charge, magnetic, electric, and anapole form factors defined as matrices in the mass basis is employed under the assumption of three-neutrino mixing. The flavor and spin change of neutrinos propagating from the source to the detector is taken into account in the form of a spin-flavor density matrix of the neutrino arriving at the detector. The potential effects of the neutrino charge radii, magnetic moments, and spin polarization in the neutrino-nucleon scattering experiments are outlined.
