强子对撞机上非标准顶胶子耦合的最新限制及其展望

Latest constraint on non-standard top-gluon couplings at hadron colliders and its future prospect

Zenro Hioki, Kazumasa Ohkuma

摘要:

结合Tevatron、7-TeV LHC和8-TeV LHC的顶对产生的最新数据,更新了由顶夸克的色磁偶极距和色电偶极距组成的非标准顶胶子耦合的约束条件.我们发现,增加最近的8-TeV的数据的分析是有效的,得到一个更强的约束色电偶极矩比一个从Tevatron和7-TeV LHC单独。我们还讨论了如何在14 TeV LHC的结果在不久的将来成为可用的非标准耦合的这些限制可以进一步改善。

英文摘要:

Constraints on the non-standard top-gluon couplings composed of the chromomagnetic- and chromoelectric-dipole moments of the top quark are updated by combining the latest data of top-pair productions from the Tevatron, 7-TeV LHC, and 8-TeV LHC. We find that adding the recent 8-TeV data to the analysis is effective to get a stronger constraint on the chromoelectric-dipole moment than the one from the Tevatron and 7-TeV LHC alone. We also discuss how those constraints on the non-standard couplings could be further improved when 14-TeV LHC results become available in the near future.
