强子对撞机上希格斯玻色子玻色子产生过程中的量子效应

Quantum Effects in Higgs-Boson Production Processes at Hadron Colliders

Michael Rauch

摘要:

寻找希格斯玻色子和扩展基本粒子物理学标准模型是欧洲核子研究中心大型强子对撞机的主要任务,该对撞机将于2008年年中开始运行。在这篇论文中,我们考虑了在大型强子对撞机上探测超对称希格斯玻色子玻色子的过程。首先编写了一个计算机程序,完成了强子截面的自动计算工具箱。利用该程序计算了伴随H-W ~+产生和伴随重夸克产生的矢量-玻色子融合产生的超对称QCD修正。修正部分地对总截面有重要贡献。此外,研究了通过三重希格斯粒子产生来测量四次希格斯粒子自耦合的可能性,发现这是一个挑战。

英文摘要:

The search for Higgs bosons and extensions of the Standard Model of Elementary Particle Physics are main tasks of the Large Hadron Collider (LHC) at CERN which will start operation mid-2008. In this thesis processes which can be used to detect supersymmetric Higgs bosons at the LHC were considered. First a computer program was written which completes the toolbox for automatic calculations of hadronic cross sections. Using this program, the supersymmetric QCD corrections to associated H-W+-production and h0-production via vector-boson fusion and in association with heavy quarks were calculated. The corrections partly give significant contributions to the total cross section. Additionally, the possibility to measure the quartic Higgs self-coupling via triple-Higgs production was investigated and found to be challenging.
