If there is Lorentz symmetry violation in the $t$ quark sector of the standard model, changes to particles’ dispersion relations might allow for the existence of stable top-flavored hadrons. Observations of the survival of high-energy $\gamma$-rays over astrophysical distances can be used to place constraints on Lorentz violation coefficients in the $t$ sector at $\sim {10}^{-4}$–${10}^{-6}$ levels of precision. \end{titlepage …

违反洛伦兹场论的顶级强子

如果在洛伦兹对称违反 $Ť$在标准模型的夸克扇区中，对粒子弥散关系的更改可能允许存在稳定的顶味强子。高能生存的观察$\gamma$天体距离上的射线可以用来约束洛伦兹违反系数中的 $Ť$ 部门 $〜{10}^{-4}$–${10}^{-6}$精度水平。\ end {titlepage…
