利用Tevatron上tt_bar事件的喷流动量的CP-奇相关

CP-odd correlations using jet momenta from tt_bar events at the Tevatron

Sudhir Kumar Gupta, G. Valencia

摘要:

本文讨论了Tevatron上tt_bar事件中喷流和轻子动量之间的T-奇关联,这种关联可用于寻找CP破坏。我们确定的轻子加喷流和纯强子顶夸克对衰变通道适合的相关性。作为CP破坏的一个例子,我们考虑的顶夸克异常耦合,包括其色电偶极矩,我们估计的限制,可以放置在Tevatron。

英文摘要:

We discuss T-odd correlations between jet and lepton momenta in tt_bar events at the Tevatron that can be used to search for CP violation. We identify correlations suitable for the lepton plus jets and purely hadronic top-quark pair decay channels. As an example of CP violation we consider the top-quark anomalous couplings, including its chromo-electric dipole moment, and we estimate the limits that can be placed at the Tevatron.
