论文摘要
我们引入了一种新的对称性，轻锥反射（LCR），该反射（LCR）互换了时机和间隔间的间隔。我们的动机是基于对称性，为什么可能存在tachyon的原因，重点是对中微子的应用。我们表明，LCR与翻译相结合，导致更大的对称性。我们构建了LCR不变的Lagrangian，并讨论了它的一些属性。在一个简单的示例中，我们在tachyon和普通颗粒之间的光谱中找到了完全对称性。我们还表明，该理论允许引入与手性对称性相关的进一步规格不变性。
We introduce a new symmetry, Light-Cone Reflection (LCR), which interchanges timelike and spacelike intervals. Our motivation is to provide a reason, based on symmetry, why tachyons might exist, with emphasis on application to neutrinos. We show that LCR, combined with translations, leads to a much larger symmetry. We construct an LCR-invariant Lagrangian, and discuss some of its properties. In a simple example, we find complete symmetry in the spectrum between tachyons and ordinary particles. We also show that the theory allows for the introduction of a further gauge invariance related to chiral symmetry.
