论文摘要
大型强子对撞机(LHC)最重要的机制之一是生产最小超对称标准模型(MSSM)的伪级Higgs玻色子(MSSM)的一种是循环诱导的Gluon融合过程$ GG \。高阶QCD校正已经在很久以前获得,结果很大。然而,到目前为止,真正的超对称(SUSY - )QCD校正仅在大型SUSY粒子质量的极限下获得。我们描述了我们对近质量依赖性的次级阶阶(NLO)susy-qCD结果的计算,并且对于一些代表性的基准点,我们的数值结果呈现。在有效的低能理论方面,我们还解决了有效的Yukawa耦合的有效顶部和底部的Yukawa耦合的处理。此外,我们还讨论了我们所计算的SUSY-QCD校正与轴向异常定理之间的关系。此外,我们将结果应用于gluonic和光子伪库级希格斯在NLO处腐烂到gg,ggγγ$。
One of the most important mechanisms at the Large Hadron Collider (LHC) for the production of the pseudoscalar Higgs boson of the Minimal Supersymmetric Standard Model (MSSM) is the loop-induced gluon fusion process $gg\to A$. The higher-order QCD corrections have been obtained a long time ago and turned out to be large. However, the genuine supersymmetric (SUSY--)QCD corrections have been obtained only in the limit of large SUSY particle masses so far. We describe our calculation of the next-to-leading-order (NLO) SUSY--QCD results with full mass dependence and present numerical results for a few representative benchmark points. We also address the treatment of the effective top and bottom Yukawa couplings, in the case of heavy SUSY particles, in terms of effective low-energy theories where the heavy degrees of freedom have been decoupled. Furthermore, we include a discussion of the relation between the SUSY--QCD corrections that we have computed and the Adler--Bardeen theorem for the axial anomaly. In addition, we apply our results to the gluonic and photonic pseudoscalar Higgs decays $A\to gg,γγ$ at NLO.
