We implement the self-interacting dark matter scenario in the NMSSM and beyond. An improved analytical estimation for the dark matter (DM) self-interacting cross section is proposed. Due to the large couplings and light mediator in SIDM scenario, the DM/mediator will go through multiple branchings if they are produced with high energy. Based on the Monte Carlo simulation of the showers in DM...

A generic heavy Higgs has both dim-4 and effective dim-6 interactions with the Standard Model (SM) particles. The former has been the focus of LHC searches in all major Higgs production modes, just as the SM one, but with negative results so far. If the heavy Higgs is connected with Beyond Standard Model (BSM) physics at a few TeV scale, its dim-6 operators will play a very important role -...

Null results from searches for new physics at the Large Hadron Collider (LHC) enforce the belief that new particles must be much heavier than the weak scale. We undertake a systematic study of the interplay between Higgs alignment and CP-violation in complex two-Higgs-doublet models (C2HDMs), which enables us to construct a CP-violating scenario where new Higgs bosons are close to the weak...

粒子物理学中的一些基本问题，如中微子质量和振荡的起源、暗物质的自然属性以及重子生成机制等，仍待回答。一种可行的方案是引入隐藏区间。目前对于隐藏区间的寻找，尤其高能量前沿的LHC实验，还没有任何明确的信号，因此人们逐渐转向了高亮度前沿对于MeV到GeV质量范围的新粒子的探测。诸如我国的BESIII等高亮度正负电子对撞机实验是高亮度前沿的重要代表。特别地，它们的运行能区对MeV到GeV质量范围的新粒子的探索有着独特的优势。本报告将针对一些典型的隐藏区间粒子，探讨BESIII等高亮度正负电子对撞机实验对于它们的探测潜力。

A high-quality axion is suggested to arise from the non-minimal unification model with the SU(6) group, due to its enhanced global symmetry. The physical axion in the model satisfies the Peccei-Quinn quality condition without fine-tuning, and can be searched for in the upcoming IAXO experiment. We also find the SU(6) model can naturally avoid the potential cosmological constraints of the...

费米实验室的缪子g-2实验对缪子的反常磁矩进行了精确的测量，首批物理结果现已公布。最新的实验结果表明缪子反常磁矩的理论预言与实验测量之间存在4.2σ的偏差，为新物理的存在提供了强有力的证据，预示着世界上可能存在新的未知粒子或者作用力。
缪子反常磁矩由两个角频率的精确测量确定。实验中，缪子受强磁场束缚在储存环内运动，通过统计缪子衰变产生的高能电子数目得到缪子的反常进动频率ω_a。利用脉冲核磁共振技术，测量质子的自旋进动频率ω_p表征强磁场的大小。结合上述两个频率以及缪子在储存环中的分布函数和其他已知常数可以精确的测量缪子的反常磁矩。首批物理结果的测量精度达到了0.46ppm，后继测量结果的精度将进一步提高，预计于2022年发布。
