一种基于GUT的多阿贝尔因子理论的简化格式

A Simplified Scheme for GUT-inspired Theories with Multiple Abelian Factors

Felix Braam, Juergen Reuter

摘要:

除了标准模型超荷外,大统一理论通常还涉及额外的阿贝尔群因子,这通常会导致环诱导混合规范动力学项。在这封信中,我们表明,在一个循环的水平,这种效果可以避免在许多情况下,通过适当的选择在群空间的基础,并提出了一个一般计划,为建设这个基础。然而,在超对称理论中,可能会出现软超对称破缺的高吉诺质量项的剩余混合。我们推广的重整化群方程的高根质量项,以考虑这种影响。在进一步的计算中,我们还对三线性软破缺耦合和软破缺标量质量平方的重整化群方程作了必要的调整。

英文摘要:

Grand Unified Theories often involve additional Abelian group factors apart from the standard model hypercharge, that generally lead to loop-induced mixing gauge kinetic terms. In this letter, we show that at the one-loop level this effect can be avoided in many cases by a suitable choice of basis in group space and present a general scheme for the construction of this basis. In supersymmetric theories however, a residual mixing in the soft SUSY breaking gaugino mass terms may appear. We generalize the renormalization group equations for the gaugino mass terms to account for this effect. In a further calculation we also present the necessary adjustments in the renormalization group equations of the trilinear soft breaking couplings and the soft breaking scalar mass squares.
