标题： Non-Perturbative Effects of Strong Magnetic Fields on Neutrino Self-energy: A New Approach

摘要： 里图斯的$E_{p}$特征函数方法被扩展到自旋-1带电粒子在恒定电磁场中的情况，并用于计算强场近似下的单环中微子自能$m_{e}^{2}\ll eB\ll M_{W}^{2}$。 在假设存在足够大的（$m_{e}^{2}\ll eB\ll m_{\mu}^{2}$）原始磁场的情况下，所得结果对早期宇宙中微子振荡的影响进行了讨论。 显示英文摘要

摘要： The Ritus' $E_{p}$ eigenfunction method is extended to the case of spin-1 charged particles in a constant electromagnetic field and used to calculate the one-loop neutrino self-energy in the strong-field approximation $m_{e}^{2}\ll eB\ll M_{W}^{2}$. The implications of the obtained results for neutrino oscillations in the early Universe, assuming the existence of a sufficiently large ($m_{e}^{2}\ll eB\ll m_{\mu}^{2}$) primordial magnetic field, are discussed.
