在不同尺度下运行夸克和轻子参数

Running quark and lepton parameters at various scales

Stefan Antusch, Vinzenz Maurer

摘要:

我们计算了夸克和轻子Yukawa耦合以及夸克混合参数在不同能量标度(MZ,1TeV,3TeV,10TeV和GUT标度)下的值和1 σ范围,为模型的建立提供了有用的输入.以上TeV的能量,我们假设最小的超对称扩展的标准模型,并包括tan(β)增强的单圈超对称阈值校正时出现匹配的SM其超对称扩展。我们计算的运行参数的大统一组织规模的价值观,以及他们的1西格玛范围内,包括超对称阈值校正和他们的影响参数化,在一个简单的方式。

英文摘要:

We calculate the values and 1 sigma ranges of the running quark and lepton Yukawa couplings as well as of the quark mixing parameters at various energy scales, i.e. at M_Z, 1 TeV, 3 TeV, 10 TeV and at the GUT scale, to provide useful input for model building. Above TeV energies, we assume the minimal supersymmetric extension of the Standard Model, and include the tan(beta)-enhanced one-loop supersymmetric threshold corrections which arise when matching the SM to its SUSY extension. We calculate the GUT scale values of the running parameters as well as their 1 sigma ranges, with the supersymmetric threshold corrections included and with their effects parametrised in a simple way.
