旋转磁化物质中具有反常磁矩的毫荷中微子
Millicharged neutrino with anomalous magnetic moment in rotating magnetized matter
摘要：
在极端背景条件下，得到了描述具有非平凡电磁性质的中微子的修正狄拉克方程的新的精确解。在准经典处理中，引入了描述中微子在磁化旋转物质中传播的有效洛伦兹力。我们预测了不同类型的相对论中微子和反中微子（不同的口味和能量）的空间分离的磁化旋转物质的恒星的效果。低能量的中微子甚至可以被困在恒星内部。我们还预言了两种新现象：一种新的中微子电磁辐射（称为“（milli）带电中微子光”，$LCν$）和一种新的中微子逃逸恒星角速度漂移机制（称为“中微子转星”机制，$νS T$）。$νS T$机制对超新星爆发的可能影响产生了中微子毫电荷$q_ν<1.3\times10^{-19}e_0$的新的天体物理极限。此外，$νS T$机制也可以用来解释脉冲星“反毛刺”和普通毛刺的起源。
英文摘要：
New exact solutions of the modified Dirac equation describing a neutrino with nontrivial electromagnetic properties in extreme background conditions are obtained. Within the quasi-classical treatment the effective Lorentz force that describes the neutrino propagation in the magnetized rotating matter is introduced. We predict the effect of the spatial separation of different types of relativistic neutrinos and antineutrinos (different in flavors and energies) by the magnetized rotating matter of a star. Low energy neutrinos can be even trapped inside the star. We also predict two new phenomena: a new type of the neutrino electromagnetic radiation (termed "Light of (milli)Charged Neutrino", $LCν$) and a new mechanism of the star angular velocity shift due to neutrinos escaping the star (termed "Neutrino Star Turning" mechanism, $νS T$). The possible impact of the $νS T$ mechanism on a supernova explosion yields a new astrophysical limit on the neutrino millicharge $q_ν<1.3\times10^{-19}e_0$. In addition, the $νS T$ mechanism can be also used to explain the origin of pulsar "anti-glitches" and ordinary glitches as well.
