中微子色散关系的一个暗能量模型

Neutrino Dispersion Relations from a Dark Energy Model

Emilio Ciuffoli, Jarah Evslin, Jie Liu, Xinmin Zhang

摘要:

我们考虑了一个中微子与标量场动力学耦合的模型,并研究了它对环境依赖的中微子速度的影响。按照通常的有效场论逻辑,这种耦合预计会出现在中微子暗能量模型中。它导致了中微子区的洛伦兹破坏。地球应力张量与标量场的耦合产生了不同于星际空间的地球中微子色散关系。

英文摘要:

We consider a model in which the neutrino is kinetically coupled to a scalar field and study its implications for environmentally dependent neutrino velocities. Following the usual effective field theory logic, this coupling is expected to arise in neutrino dark energy models. It leads to a Lorentz violation in the neutrino sector. The coupling of the scalar field to the stress tensor of the Earth yields terrestrial neutrino dispersion relations distinct from those in interstellar space.
