论文摘要
虽然对核子衰变的观察通常是大统一理论（肠）的吸烟枪，但各种通道的衰减速率之间的比率具有有关特定肠模型实现的丰富信息。为了在超对称（SUSY）胆量的上下文中研究肠道模型的这种指纹，我们介绍了软件工具\ texttt {susytcproton}，这是模块\ texttt {susytc}的扩展，可与\ texttt {reap}套装一起使用。它允许从相关尺寸五个肠道算子计算核子衰减速率，包括肠道尺度，包括在SUSY尺度上进行完整的环。作为应用程序，我们研究了具有不同风味结构的两个示例肠道玩具模型的指纹，进行了MCMC分析，以包括带电的费米昂质量和CKM混合参数的实验不确定性。尽管这两个玩具模型都提供了低能数据的良好拟合，但我们展示了如何通过其对核子衰减速率比率的预测来区分它们。与\ texttt {susytcproton}一起，我们还将其他模块\ texttt {protondecay}公开。它可以独立于\ texttt {creap}独立使用，并允许从给定的$ d = 5 $和$ d = 6 $运算符系数计算核子衰减率（接受SLHA格式的$ d = 5 $ case所需的SUSY输入）。 $ d = 6 $功能也可用于计算非恐惧胆量中的核子衰减。
While the observation of nucleon decay would be a smoking gun of Grand Unified Theories (GUTs) in general, the ratios between the decay rates of the various channels carry rich information about the specific GUT model realization. To investigate this fingerprint of GUT models in the context of supersymmetric (SUSY) GUTs, we present the software tool \texttt{SusyTCProton}, which is an extension of the module \texttt{SusyTC} to be used with the \texttt{REAP} package. It allows to calculate nucleon decay rates from the relevant dimension five GUT operators specified at the GUT scale, including the full loop-dressing at the SUSY scale. As an application, we investigate the fingerprints of two example GUT toy models with different flavor structures, performing an MCMC analysis to include the experimental uncertainties for the charged fermion masses and CKM mixing parameters. While both toy models provide equally good fits to the low energy data, we show how they could be distinguished via their predictions of ratios for nucleon decay rates. Together with \texttt{SusyTCProton} we also make the additional module \texttt{ProtonDecay} public. It can be used independently from \texttt{REAP} and allows to calculate nucleon decay rates from given $D=5$ and $D=6$ operator coefficients (accepting the required SUSY input for the $D=5$ case in SLHA format). The $D=6$ functionality can also be used to calculate nucleon decay in non-SUSY GUTs.
