摘要

标准模型希格斯玻色子有多种衰变模式，位于欧洲核子研究中心大型强子对撞机上的CMS和ATLAS实验已经测量到了其中一些衰变模式。本文计算了标准模型希格斯玻色子通过直接碎片机制衰变成介子的过程。在这种方法中，希格斯玻色子首先衰变成（c）和（b）对，然后重夸克直接碎裂成（D^{*\pm }）介子。通过考虑 $D^{*\pm }$ 碎片函数中的 NLO 和 NNLO 修正，计算了 SM 希格斯玻色子进入 $D^{*\pm }$ 介子的分支率。

Higgs Boson Decay into $D^{*\pm }$ Meson Via Fragmentation

The standard model Higgs boson has various decay modes, some of which have been measured in the CMS and ATLAS experiments, located at the Large Hadron Collider at CERN. This paper, calculates the decay of the standard model Higgs boson into $D^{*\pm }$ meson through the mechanism direct fragmentation. In this approach, the Higgs boson, first decays into $c\bar{c}$ and $b\bar{b}$ pairs, and then the heavy quarks fragment directly into $D^{*\pm }$ meson. The branching ratios of the SM Higgs boson into $D^{*\pm }$ meson have been calculated by considering NLO and NNLO corrections in the fragmentation functions of $D^{*\pm }$.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
