标量快子场拉格朗日量和标量快子费曼传播子的洛伦兹不变和洛伦兹非不变性质
Lorentz-invariant and Lorentz-non-invariant aspects of a scalar tachyon field Lagrangian and the scalar tachyon Feynman propagator
摘要：
超光速粒子（快子）的相容理论可以建立取代标准的洛伦兹不变的方法的量子场论的快子的洛伦兹协变的一个，调用的概念，首选的参考系。这是因果守恒所强加的一个强制性条件。本文研究了标量快子场的洛伦兹破坏（但洛伦兹协变）拉格朗日量的一些特征。结果表明，快子场的运动方程和由它导出的费曼传播子是洛伦兹不变量的，而所提出的快子场模型的洛伦兹对称性可以定义为协变破缺.
英文摘要：
A consistent theory of faster-than-light particles (tachyons) can be built replacing the standard Lorentz-invariant approach to the quantum field theory of tachyons by the Lorentz-covariant one, invoking a concept of the preferred reference frame. This is a mandatory condition imposed by the causality conservation. In this article some features of a Lorentz-violating (but Lorentz-covariant) Lagrangian of a scalar tachyon field are considered. It is shown that the equation of motion and Feynman propagator resulting from it are Lorentz-invariant, while the Lorentz symmetry of the suggested tachyon field model can be defined as covariantly broken.
