对$CPT$与Lorentz破坏关系质疑的注记

Remarks on a challenge to the relation between $CPT$ and Lorentz violation

O. W. Greenberg

摘要:

对我的定理[arXiv:hep-ph/0201258]的异议[arXiv:1103.0168],即违反$CPT$对称性意味着违反洛伦兹协方差,是基于一个非局部模型,在这个模型中,时间序乘积没有很好地定义。我用时间序列乘积的协方差作为洛伦兹协方差的条件,因此提出的异议与我的结果无关。

英文摘要:

The objection [arXiv:1103.0168] to my theorem [arXiv:hep-ph/0201258] that violation of $CPT$ symmetry implies violation of Lorentz covariance is based on a nonlocal model in which time-ordered products are not well defined. I used covariance of time-ordered products as the condition for Lorentz covariance; therefore the proposed objection is not relevant to my result.
