顶部不对称性和寻找与单顶部有关的轻强子共振

Top asymmetry and the search for a light hadronic resonance in association with single top

Sunghoon Jung, Aaron Pierce, James D. Wells

摘要:

轻的$t$通道变味规范玻色子$\Vp$与质量为$\sim m_{top}$的交换仍然是Tevatron上顶夸克产生的异常前后不对称的主要解释。不像其他想法,包括较重的$t$ -通道介体,轻$\Vp$模型不容易在$\mtt$分布中看到。我们提倡一种更有希望的战略。虽然目前的分析在强子对撞机可能不敏感,我们建议寻找一个$jj$共振与单顶,可能会发现在现有的数据。在这个样品中轻子电荷不对称性的偏差也应该存在。

英文摘要:

The exchange of a light $t$-channel flavor-changing gauge boson, $\Vp$, with mass $\sim m_{top}$ remains a leading explanation for the anomalous forward backward asymmetry in top quark production at the Tevatron. Unlike other ideas, including heavier $t$-channel mediators, the light $\Vp$ model is not easily seen in the $\mtt$ distribution. We advocate a more promising strategy. While current analyses at hadron colliders may not be sensitive, we propose searching for a $jj$ resonance in association with single top that may allow discovery in existing data. Deviations in the lepton charge asymmetry in this sample should also be present.
