β衰变中相干味本征态的相互作用和振荡

Interactions and oscillations of coherent flavor eigenstates in beta decay

Cheng-Yang Lee

摘要:

由布拉松和维泰洛开创的理论将大质量中微子描述为扩展标准模型中的广义相干味本征态。本文计算了Blasone-Vitiello理论中双中微子模型的中子β衰变谱。对于相对论中微子,所得谱与标准模型一致。然而,当电子的动能接近终点能量时,存在差异。在未来的实验中测量的差异的可能性进行了讨论。

英文摘要:

The theory pioneered by Blasone and Vitiello describes massive neutrinos as generalized coherent flavor eigenstates within the extended Standard Model. In this paper, we compute the neutron beta decay spectrum for the Blasone-Vitiello theory in a model with two neutrinos. For relativistic neutrinos, the obtained spectrum is in agreement with the Standard Model. However, there are discrepancies when the kinetic energy of the electron is close to the end point energy. The possibility of measuring the discrepancies in future experiments is discussed.
