Determining the CP property of the Higgs boson is important for a precision test of the Standard Model as well as for the search for new physics. We propose a novel jet substructure observable based on the azimuthal anisotropy in a linearly polarized gluon jet that is produced in association with a Higgs boson at hadron colliders, and demonstrate that it provides a new CP-odd observable for determining the CP property of the Higgs-top interaction. We introduce a factorization formalism to define a polarized gluon jet function with the insertion of an infrared-safe azimuthal observable to capture the linear polarization.

通过新颖的射流子结构可观察确定[公式省略]耦合的CP属性


确定希格斯玻色子的 CP 属性对于标准模型的精确测试以及寻找新物理学非常重要。我们提出了一种基于线性偏振胶子射流中的方位各向异性的新型射流子结构可观测量，该线偏振胶子射流是与强子对撞机中的希格斯玻色子相关产生的，并证明它提供了一种新的 CP 奇可观测量来确定希格斯玻色子的 CP 属性- 顶部互动。我们引入因式分解形式来定义偏振胶子射流函数，并插入红外安全方位角可观测量来捕获线性偏振。
