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.

今年，我一直在研究 Nambu-Goldstone (NG) 希格斯大统一理论 (GUT) 模型。我们研究了具有全局 SU(6) 对称性（包括 SU(5)）作为子群的超对称 (SUSY) SU(5) GUT 模型，以将希格斯粒子解释为 NG 希格斯粒子并解决双线态-三线态分裂问题。我们使用重正化群方程用 SUSY 参数表示 GUT 参数，并计算不同软 SUSY 破坏场景下的质子衰变。我还在做另一个关于使用手性微扰理论计算质子衰变的项目。我们正在尝试使用手性微扰理论来改进不同通道的质子衰变结果。它有助于将实验范围与理论预测联系起来，以测试 GUT 模型。
