Dark Neutrino Moments From Light Loops

Gonzalo Herrera, Ian M. Shoemaker

AI总结:

本研究提出中微子可通过含无质量暗光子的单圈图获得增强型暗电磁矩且规避相关约束,模型预言可通过对太阳中微子流敏感的暗物质直接探测实验检验。

摘要:

活性中微子和惰性中微子可通过含无质量暗光子与圈中新轻粒子的单圈图获得“暗矩”。由于暗光子与标准模型光子之间存在动力学混合,中微子会获得有效电磁矩。该机制可实现增强的电磁矩,且能规避对直接带电磁荷粒子的限制。我们表明,在广泛的参数空间区域内,该模型对活性和惰性中微子的无电极矩和磁矩给出了可检验的预言,可通过对太阳中微子流敏感的暗物质直接探测实验进行验证。

英文摘要:

Active and sterile neutrinos may acquire "dark moments" via one-loop diagrams with a massless dark photon and new light particles in the loop. Due to the kinetic mixing between the dark photon and the Standard Model photon, neutrinos would obtain effective electromagnetic moments. This mechanism allows for enhanced electromagnetic moments that can evade constraints on particles directly charged under electromagnetism. We show that in a wide region of parameter space, the model features testable predictions for the anapole and magnetic moment of active and sterile neutrinos with dark matter direct detection experiments sensitive to the solar neutrino flux.
