关于洛伦兹破坏的三个问题
Three Questions on Lorentz Violation
摘要：
我们回顾了洛伦兹破坏的两种最广泛使用的方法-标准模型扩展和非对易场论-的基础知识，并详细讨论了同步辐射的修改光谱的例子。受洛伦兹对称性这样一个基本问题的启发，我们提出了三个问题：寻找洛伦兹破坏的背后是什么？弦论是物理理论吗？超对称性有替代品吗？
英文摘要：
We review the basics of the two most widely used approaches to Lorentz violation - the Stardard Model Extension and Noncommutative Field Theory - and discuss in some detail the example of the modified spectrum of the synchrotron radiation. Motivated by touching upon such a fundamental issue as Lorentz symmetry, we ask three questions: What is behind the search for Lorentz violation? Is String Theory a physical theory? Is there an alternative to Supersymmetry?
