大质量中微子大小的经典下界

A classical lower bound on the size of a massive neutrino

E. Sadurní, A. Rosado, S. Rosado-Navarro

摘要:

在本文中,我们用以下方法计算了一个大质量中微子的大小。我们通过中微子-电子相互作用,$via$经典磁偶极-偶极相互作用,使用它的质量,自旋和磁矩进行计算。因此,我们的估计是通过模拟低能电弱散射过程$ν_l$ - $l^{\prime}$得到的。这导致了令人惊讶的准确结果,其差异小于一个数量级的更详细的计算与基于中微子电荷半径和$ν_l$ - $l^{\prime}$散射过程的单圈校正。由此产生的估计是口味盲和规格独立的建设。我们还发现,我们的下限是低于报告的实验上限的电子中微子带电半径。所以我们得到了中微子大小的限制范围。

英文摘要:

In this paper, we calculate the size of a massive neutrino in the following approach. We perform our calculation using its mass, spin, and magnetic moment through the neutrino-electron interaction, $via$ the classical magnetic dipole-dipole interaction. Thus, our estimate is obtained by mimicking the low-energy electroweak scattering process $ν_l$-$l^{\prime}$. This leads to surprisingly accurate result which differs in less than one order of magnitude of more detailed calculations with one-loop corrections based on the neutrino charge radius and the $ν_l$-$l^{\prime}$ scattering process. The resulting estimates are flavour-blind and gauge independent by construction. We also find that our lower bound is below the reported experimental upper bound on the electron neutrino charged radius. So we obtained a constraining range for the neutrino size.
