论文摘要
我们在高温下研究极度炎热宇宙和恒星的超密集介质的磁磁矩。带电瘦素的异常磁矩与其质量成反比，而中性瘦素的诱导偶极矩与质量成正比。中性的大量点颗粒将非零磁矩作为高阶效应，比其同一风味伴侣的带电粒子的异常磁矩小。所有瘦素都因与培养基的相互作用而获得一些额外的质量，并相应地影响磁矩。由于温度和化学势依赖性质量，我们比较了对各种瘦素的磁矩的贡献。结果表明，磁矩贡献对于较轻的瘦素和沉重的中微子是不可显着的。这些计算对于研究早期宇宙和超密集恒星培养基中的颗粒传播非常重要。
We study the magnetic moment of leptons in extremely hot universe and superdense media of stars at high temperatures. Anomalous magnetic moment of charged leptons is inversely proportional to its mass, whereas, the induced dipole moment of neutral leptons is directly proportional to their mass. Neutral massive point particles exert nonzero magnetic moment as a higher order effect, which is smaller than the anomalous magnetic moment of a charged particle of their same flavor partner. All leptons acquire some extra mass due to their interaction with the medium and affect the magnetic moment accordingly. We compare the contribution to the magnetic moment of various leptons due to their temperature and chemical potential dependent masses. It is shown that the magnetic moment contributions are non-ignorable for lighter leptons and heavy neutrinos. These calculations are very important to study particle propagation in the early universe and in superdense stellar media.
