Meson scattering in a Lorentz-violating scalar QED at finite temperature

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 temper-ature 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. (C) 2022 Elsevier Inc. All rights reserved.

This paper investigates the influence of nonzero temperature on the differential cross-section for mesons scattering in a Lorentz-violating extension of the scalar electrodynamics. It is found that the corrections induced on the meson scattering are very large in the high-temperature regime, and temperature effects may contribute to new constraints on the Lorentz-violating parameters.
