引力能区分狄拉克中微子和马约拉纳中微子吗?

Can Gravity Distinguish between Dirac and Majorana Neutrinos?

S. A. Alavi, A. Abbasnezhad

摘要:

Menon和Thalappilil研究了中微子与引力场的相互作用。他们推导出马约拉纳中微子和狄拉克中微子之间的一些理论差异。然后他们证明,尽管存在这些理论上的差异,就实验而言,它们实际上是无法区分的。本文研究了中微子与弱引力场的二阶相互作用。我们发现,出现了新的中微子引力形状因子,这是在一阶计算中没有的,所以从理论的角度来看,这两种中微子之间有更多的差异比在一阶,但我们表明,同样,他们是不可区分的实验。

英文摘要:

The interaction of neutrinos with gravitational fields in the weak field regime at one loop to the leading order has been studied by Menon and Thalappilil. They deduced some theoretical differences between the Majorana and Dirac neutrinos. Then they proved that, in spite of these theoretical differences, as far as experiments are concerned, they would be virtually indistinguishable. We study the interaction of neutrinos with weak gravitational fields to the second order (at two loops). We show that there appear new neutrino gravitational form factors which were absent in the first-order calculations, so from a theoretical point of view there are more differences between the two kinds of neutrinos than in the first order, but we show that likewise they are indistinguishable experimentally.
