Abstract

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.

通过新型射流子结构观测指标确定htt¯耦合的CP特性
确定希格斯玻色子的 CP 特性对于精确检验标准模型和寻找新物理非常重要。我们根据在强子对撞机中与希格斯玻色子一起产生的线性极化胶子射流中的方位各向异性,提出了一种新的射流子结构观测指标,并证明它为确定希格斯顶相互作用的 CP 特性提供了一种新的 CP-odd 观测指标。我们引入了一个因子化形式主义来定义极化胶子射流函数,并插入了一个红外安全方位观测值来捕捉线性极化。
