摘要:

为了可靠地预测目前和未来高能对撞机上的NMSSM希格斯玻色子玻色子签名,正确区分NMSSM和MSSM希格斯扇区,包括高阶修正在内的希格斯玻色子玻色子质量的精确知识是必不可少的。本文用三种不同的重整化方案计算了中性NMSSM希格斯玻色子质量和混合的单圈修正。除了现有文献中的$\bar{DR}$重整化方案外,还采用了另外两种方案。此外,还研究了顶夸克质量的依赖性.由此产生的希格斯质量修正进行了比较,由于缺少高阶修正的剩余理论误差可以估计为10%的顺序。

英文摘要:

For a reliable prediction of the NMSSM Higgs boson signatures at present and future high-energy colliders and a proper distinction of the NMSSM and MSSM Higgs sector the precise knowledge of the Higgs boson masses including higher-order corrections is indispensable. In this paper, the one-loop corrections to the neutral NMSSM Higgs boson masses and mixings are calculated in three different renormalisation schemes. In addition to the $\bar{DR}$ renormalisation scheme, existing in the literature, two other schemes are adopted. Furthermore, the dependence on the value of the top quark mass is investigated. The resulting Higgs mass corrections have been compared and the residual theory error due to missing higher-order corrections can be estimated to be of the order of 10%.
