标题： Non-Zero Electric Charge of the Neutrino and the Solar Neutrino Problem

摘要： 最近的研究表明，在包括最小标准模型在内的多种规范理论中，中微子可以具有非零电荷。假设中微子具有非零电荷，我们提出了一种解决太阳中微子问题的新方法。 关键思想是带电中微子在穿越太阳磁场时会受到洛伦兹力的偏转。 这种偏转会导致太阳中微子流的各向异性。 由于这种各向异性，与标准太阳模型的预测相比，地球上观测到的太阳中微子通量可能会减少。 这一机制完全是经典的，不需要中微子振荡、自旋翻转或中微子衰变。 我们定性地讨论了我们的场景对当前和未来太阳中微子实验的影响，以及我们的机制与其他提出的解决方案之间的差异。 显示英文摘要

摘要： It has recently been shown that the neutrino can have non-zero electric charge in a number of gauge theories, including the Minimal Standard Model. Assuming non-zero neutrino charge, we develop a new approach to the solar neutrino problem. The key idea is that the charged neutrinos will be deflected by the Lorentz force while they are crossing the solar magnetic fields. Such a deflection will result in the anisotropy of the solar neutrino flux. Because of this anisotropy, the solar neutrino flux registered on earth can be reduced as compared to the Standard Solar Model prediction. The mechanism is purely classical and does not require neutrino oscillations, spin-flip or neutrino decay. We discuss qualitatively the consequences of our scenario for present and future solar neutrino experiments as well as differences between our mechanism and other proposed solutions.
