摘要:

在超对称大统一理论中,在双圈水平上计算了六维质子衰变有效算符的重整化因子。为了这个目的,我们使用以前的结果,其中对有效K在双环水平上评估Ahler势。数值的因素的情况下,最小的超对称SU(5)大统一模型。我们还导出了K中任意高维算子的单圈重整化因子的简单公式ahler势,假设它们是由规范相互作用引起的。

英文摘要:

The renormalization factors of the dimension-six effective operators for proton decay are evaluated at two-loop level in the supersymmetric grand unified theories. For this purpose, we use the previous results in which the quantum corrections to the effective Kahler potential are evaluated at two-loop level. Numerical values for the factors are presented in the case of the minimal supersymmetric SU(5) grand unified model. We also derive a simple formula for the one-loop renormalization factors for any higher-dimensional operators in the Kahler potential, assuming that they are induced by the gauge interactions.
