Abstract

In this paper we examine the thermal effects into the \(e^{+}e^{-}\rightarrow \ell ^{+}\ell ^{-}\) scattering in a non-Hermitian extension of QED. We compute the thermal contributions to this scattering cross section within the Thermo Field Dynamics approach. In order to highlight the non-Hermitian effects we have considered some limits of interest: i) zero-temperature limit and high-energy limit and ii) high-temperature regime. Since this type of scattering possesses accurate experimental data for the cross section (for muon and tau at the final state) it can be used to set stringent bounds upon the non-Hermitian parameters.

热效应下的非赫米提电子-正电子湮灭
本文研究了QED的非厄米扩展中\(e^{+}e^{-}\rightarrow \ell ^{+}\ell ^{-}\)散射的热效应。我们用热场动力学方法计算了散射截面的热贡献。为了突出非厄米效应,我们考虑了一些感兴趣的极限:i)零温度极限和高能极限以及ii)高温状态。由于这种类型的散射具有精确的横截面实验数据(对于最终状态的μ子和τ子),因此可以用来设置非厄米参数的严格界限。
