摘要

本文的重点是对标准模型扩展（SME）的费米子部门进行额外检验。在此背景下，我们的主要工作是研究洛伦兹对称性违反（LSV）对克莱因悖论、齐特布格及其与凝聚态物理、原子物理和天体物理学相关的现象学的影响。最后，我们讨论了 LSV 在狄拉克方程中的特殊实现，考虑了费米子线性动量中存在的尺度因子导致的空间与时间的不对称，但这并不影响其时间导数。我们将进一步扩展这种不对称在尺度因子变得与时空相关的情况下的影响，利用散射光子的费米子的扩展色散关系计算其对康普顿效应运动学的影响。

Re-assessing special aspects of Dirac fermions in presence of Lorentz-symmetry violation

This paper focuses on additional inspections concerning the fermionic sector of the Standard Model Extension (SME). In this context, our main effort in this contribution is to investigate effects of Lorentz-symmetry violation (LSV) on the Klein Paradox, the Zitterbewegung and its phenomenology in connection to Condensed Matter Physics, Atomic Physics, and Astrophysics. Finally, we discuss a particular realization of LSV in the Dirac equation, considering an asymmetry between space and time due to a scale factor present in the linear momentum of the fermion, but which does not touch its time derivative. We go further and extend the implications of this asymmetry in the situation the scale factor becomes space–time dependent to compute its influence on the kinematics of the Compton effect with the extended dispersion relation for the fermion that scatters the photon.
