High-precision tests of local Lorentz invariance, via monitoring of the sidereal time variation of the photon energies emitted by ultrarelativistic heavy-ion beams and of the beam momentum, are proposed. This paper includes descriptions of the physics ideas and the concept for the detector. The experiment results will allow high-precision tests of LLI via anisotropy of the maximum attainable speed of a photon and an ion. The projected accuracy for the asymmetries interpreted in the framework of the anisotropic relativistic mechanics corresponds to the limit on sidereal time variation of the one-way maximum attainable speed at the levels between 10⁻¹⁴ and 10⁻¹⁷.

伽马工厂中光子和强子的局部洛伦兹不变性测试

提出了通过监测超相对论重离子束发射的光子能量和束流动量的恒星时变化，对局部洛伦兹不变性进行高精度测试。本文包括对物理思想和探测器概念的描述。实验结果将允许通过光子和离子的最大可达到速度的各向异性对 LLI 进行高精度测试。^{在各向异性相对论力学框架中解释的不对称性的预测精度对应于在 10 -14}和 10 ^-17之间的水平上单向最大可达到速度的恒星时变化的限制。
