论文摘要
在该过程中底部夸克的分布$ e^+ e^ - \ to t \，\ bar {t} \ to b \，w^+ \，\ bar {t} $在$ e^+ e^ - $能量上对应于与紧凑型线性界面的第一个构造阶段相对应的能量。 $ e^+ e^ - \ to b \ ldots $的横截面是$ b $ quark能量的功能，相对于电子束的方向，得出了和计算。通过修改的$γt\ bar {t} $和$ z t \ bar {t} $耦合，它们自然出现在有效的现场理论中。除了横截面外，还计算了能量和角不对称。这些观察力对$ e^+ e^ - $能量的依赖性是计算的，并研究了这种依赖性的特征。
The distributions of the bottom quark in the process $e^+ e^- \to t \, \bar{t} \to b \, W^+ \, \bar{t}$ are considered at the $e^+ e^-$ energy corresponding to the first construction stage of the Compact Linear Collider. The cross sections of $e^+ e^- \to b \ldots$, as functions of the $b$-quark energy and angle with respect to the direction of the electron beam, are derived and calculated. The effects of physics beyond the Standard Model are included via the modified $γt \bar{t}$ and $Z t \bar{t}$ couplings which naturally appear in effective field theories. In addition to the cross sections, the energy and angular asymmetries are calculated. The dependence of these observables on the $e^+ e^-$ energy is calculated, and features of this dependence are investigated.
