论文摘要
我们提出了一个可观察到的新的二面角，以测量在14〜TEV LHC处的$ t \ bar {t} h $生产中顶级夸克和希格斯玻色相互作用的CP属性。我们考虑了希格斯玻色子的两种衰减模式，$ h \ to b \ bar {b} $和$ h \ toγγ$，并表明二面角分布能够以95 \％的置信度以$ \ sim 180〜$ sim 180〜\ fm fusportive cp-even和cp-odd假设以95 \％的置信度区分。
We propose a new dihedral angle observable to measure the CP property of the interaction of top quark and Higgs boson in the $t\bar{t}H$ production at the 14~TeV LHC. We consider two decay modes of the Higgs boson, $H\to b\bar{b}$ and $H\to γγ$ and show that the dihedral angle distribution is able to distinguish the CP-even and the CP-odd hypothesis at 95\% confidence level with an integrated luminosity of $\sim 180~{\rm fb}^{-1}$.
