标题： Constraining Anomalous Top Quark Couplings at the Tevatron

摘要： 我们探讨了反常色磁矩$\kappa$对费米实验室顶夸克对产生特性的影响。 我们发现对于质量在170 GeV范围内的顶夸克，目前的搜索正在探测$\kappa$的数量级为${1 \over 3}$。 对于此范围内的$\kappa$，我们发现两者在$q \bar q,~gg \to t \bar t$产生截面方面都有显著增强。 一旦顶夸克被确认且量子色动力学不确定性得到控制，未来费米实验室的高统计量测量最终将对$\kappa$的数值敏感，其大小小于0.10-0.15。 我们讨论一类标量技术色模型，这些模型可能在产生$m_t$的同时产生$\kappa$的较大值。 显示英文摘要

摘要： We explore the influence of an anomalous chromomagnetic moment, $\kappa$, onthe production characteristics of top quark pairs at the Tevatron. We find that for top quarks in the 170 GeV mass range, present searches are probing values of $\kappa$ of order ${1 \over 3}$. For $\kappa$'s in this range we find that significant enhancements in the both the $q \bar q,~gg \to t \bar t$ production cross sections are obtained. Once top has been verified and QCD uncertainties are under control, future high statistics measurements at the Tevatron will eventually be sensitive to values of $\kappa$ with magnitudes smaller than 0.10-0.15. We discuss a class of scalar technicolor models which may produce large values of $\kappa$ in conjunction with generation of $m_t$.
