摘要

人们还考虑了不同的过程来研究洛伦兹对称违反的影响，并确定了洛伦兹违反系数大小的各种界限。在本工作中，我们首次研究了洛伦兹违反项在两种不同的情况下对重介子的碎片函数（FFs）的影响，这两种情况对应于量子色动力学理论（QCD）中的轴向和矢量非极小耦合。我们的分析结果可以用于研究洛伦兹对称违逆对高能对撞机强子产生过程的影响。

The effect of Lorentz symmetry violation on the hadron fragmentation function

Different processes have been yet considered to investigate the effects of Lorentz symmetry violation and various bounds have been determined for the magnitude of Lorentz violation (LV) coefficients. In the present work we study, for the first time, the effect of Lorentz-violating terms on the fragmentation functions (FFs) of heavy mesons in two distinct cases correspondent to axial and vectorial nonminimal couplings in the theory of quantum chromodynamics (QCD). Our analytical results for heavy meson FFs in the framework of LV can be used to study the effect of Lorentz symmetry violation on hadron production processes in high energy colliders.
