标准弱相互作用中产生的中微子是Dirac粒子还是Majorana粒子？
Is neutrino produced in standard weak interactions a Dirac or Majorana particle?
摘要：
本文研究了在标准的弱相互作用中产生什么类型的中微子（狄拉克中微子或马约拉纳中微子）？结果表明，在这些相互作用中，只能产生Dirac中微子，而不能产生Majorana中微子。这意味着这个中微子将在另一种类型的相互作用中产生。也就是说，Majorana中微子将在区分自旋投影但不能区分中微子（粒子）和反中微子（反粒子）的相互作用中产生。这种相互作用尚未被发现。因此，高精度的实验对探测无中微子双衰变具有重要意义。
英文摘要：
This work considers the following problem: what type (Dirac or Majorana) of neutrinos is produced in standard weak interactions? It is concluded that only Dirac neutrinos but not Majorana neutrinos can be produced in these interactions. It means that this neutrino will be produced in another type of interaction. Namely, Majorana neutrino will be produced in the interaction which differentiates spin projections but cannot differentiate neutrino (particle) from antineutrino (antiparticle). This interaction has not been discovered yet. Therefore experiments with very high precision are important to detect the neutrinoless double decay.
