In this year, I have been working on Nambu-Goldstone (NG) Higgs grand unified theories (GUT) models. We studied supersymmetric (SUSY) SU(5) GUT model with a global SU(6) symmetry including SU(5) as a subgroup to explain Higgs as NG Higgs particles and to solve the doublet-triplet splitting problem. We used renormalization group equations to represent the GUT parameters by the SUSY parameters and calculated the proton decay with different soft-SUSY-breaking scenarios.I am also doing another project about the calculation of proton decay using chiral perturbation theory. We are trying to use chiral perturbation theory to improve the results of proton decays for different channels. It could help to connect the experimental bounds to theoretical predictions to test GUT models.

在今年，我一直在研究Nambu-Goldstone（NG）Higgs Grand Unified Theories（GUT）模型。我们研究了具有全局su（6）对称性的超对称性（SUSY）SU（5）肠道模型，包括SU（5）作为一个子组，以解释Higgs为Ng Higgs颗粒并解决Doublet-Triplet分解问题。我们使用重新归一化组方程来表示肠道参数，并使用不同的柔软感染的场景计算了质子衰减。我们正在尝试使用手性扰动理论来改善不同通道的质子衰变结果。它可以帮助将实验界限与理论预测联系起来，以测试肠道模型。
