通过胶子聚变产生MSSM希格斯玻色子玻色子:大的胶子质量极限

MSSM Higgs Boson Production via Gluon Fusion: The Large Gluino Mass Limit

Margarete Mühlleitner, Heidi Rzehak, Michael Spira

摘要:

标量MSSM希格斯玻色子玻色子通过胶子融合gg -> h,H的产生是由重夸克和夸克环介导的。事实证明,这些过程的高阶QCD修正很大。最近计算了全超对称QCD修正。在大超对称质量极限中出现了一个概念性问题,即如何正确处理大胶子质量极限。在这项工作中,我们将描述一致的重胶子效应的解耦,并导出解耦胶子的有效拉格朗日量。

英文摘要:

Scalar MSSM Higgs boson production via gluon fusion gg -> h,H is mediated by heavy quark and squark loops. The higher order QCD corrections to these processes turn out to be large. The full supersymmetric QCD corrections have been calculated recently. In the limit of large SUSY masses a conceptual problem appears, i.e. the proper treatment of the large gluino mass limit. In this work we will describe the consistent decoupling of heavy gluino effects and derive the effective Lagrangian for decoupled gluinos.
