论文摘要
本文研究了非零温度如何影响标量电动力学的洛伦兹侵入性扩展中介体散射的差分横截面。我们最初讨论模型的某些特征，并提取零温度Feynman规则。使用热场动力学（TFD）形式主义引入温度效应。结果表明，在高温状态下，在介子散射上诱导的校正非常大。此外，我们的结果还表明，温度影响可能有助于对洛伦兹侵入参数的新约束。
This paper investigates how the nonzero temperature affects the differential cross-section for mesons scattering in a Lorentz-violating extension of the scalar electrodynamics. We initially discuss some features of the model and extract the zero temperature Feynman rules. Temperature effects are introduced using the Thermo Field Dynamics (TFD) formalism. It is shown that the corrections induced on the meson scattering are very large in the high-temperature regime. Furthermore, our results also suggest that temperature effects may contribute to new constraints on the Lorentz-violating parameters.
