论文摘要
在粒子物理的标准模型的各种扩展中，即使在没有中微子质量的三代标准模型中，中微子也可以具有很小的电荷。在审查了允许出现此类指控的理论场景之后，我们讨论了现有的观察限制，并为Muon和Tau Neutminos的指控提供了新的严格直接上限。我们还指出了一种从中微子电荷上的风味 - 全面结合，这是从弱重力猜想中获得的，这是基于重力是最弱力的假设。我们终于在基于磁铁的天体物理观测值的中微子费用上提出了一种新的风味上微子上微子的上微子上微子。
In various extensions of the Standard Model of particle physics, and intriguingly even in the three-generation Standard Model without neutrino masses, neutrinos are allowed to have very tiny electric charges. After a review of the theoretical scenarios that allow the emergence of such charges, we discuss the existing observational limits and we derive new stringent direct upper bounds for the charges of the muon and tau neutrinos. We also point out a flavor-universal lower bound on neutrino charges which is obtained from the weak gravity conjecture, that is based on the hypothesis that gravity is the weakest force. We finally present a new flavor-universal upper bound on neutrino charges based on astrophysical observations of Magnetars.
