MAPS是高能物理实验中内径迹探测器重要的实现方式之一，其具有物质量低、空间分辨高等特点。兼具时间测量和能量测量功能的MAPS通常被称作5D MAPS，有利于进一步提高径迹重建效率，但也给芯片设计带来了更大的挑战。本研究面向下一代高亮度电子对撞机内径迹探测器，基于不同工艺和优化方案开展低功耗 5D MAPS的设计工作。其中在GSMC130 nm工艺下，像素单元尺寸为33.2 μm×33.2 μm，通过对多个像素单元的数字输出错位做”或”并编码的方式合并读出通道，并基于超级像素进行数据读出，从而降低数字功耗。同时，超级像素内集成500 MHz启停型VCO用于细时间计数，使时间测量精度大幅降低到2ns，且不产生额外静态功耗。外围电路包含击中信息的读出、时间戳校准、汇总、缓存、组帧、编码和高速串行化等功能。预计芯片总功耗小于60 mW/cm²。

In this work, we extend the two-flavor Nambu--Jona-Lasinio model to one capable of exploring quark and nuclear matter consistently. With an extra term standing for quark-nucleon interactions, nucleons could automatically emerge as color-singlet three-quark entities by following a process similar to mesons. Besides the quark part in mean field approximation, both mesons and nucleons could...

磁单极子作为大统一理论预言的基本粒子，在解释电荷量子化和宇宙暴胀模型等方面扮演着至关重要的角色。SCEP实验组提出了一种基于室温线圈和塑料闪烁体的符合探测手段，用以探测磁单极子。其中利用线圈探测的基本原理是通过探测磁单极子穿过线圈时产生的感应信号，这对信噪比有着严格的要求。为此，SCEP实验组提出了两种探测感应信号的方案——ADC读出方案和磁力仪读出方案。本报告将围绕这两种方案展开，介绍它们的基本结构，并详细阐述感应信号及各部分噪声的特征。为了提高信噪比，我们进行了初步的优化设计，并给出了最终的预期信噪比。

In this talk I will review our recent efforts to understand the polarized Transverse-Momentum-Dependent fragmentaion functions (TMD FFs) . Recent BELLE results on $\Lambda/\bar\Lambda$ polarization in $e^+e^-$-annihilations stimulate a series of progress from several groups to understand the polarized TMD FF $D_{1T}^\perp$. Based on the fundamental isospin symmetry of QCD, we propose a new...

北京谱仪（BESIII）实验是目前国际上唯一运行在𝜏−粲能区的大型粒子物理实验装置，为𝜏−粲能区的物理课题提供了重要的研究平台。𝜏−粲能区的物理过程，末态中含有较多的强子成分，因此粒子鉴别非常重要。

目前BESIII实验通过联合dE/dx和飞行时间实现粒子鉴别，由于没有切伦科夫探测器，因此在高动量区域的粒子鉴别效率较低，不能充分满足物理需求。所以，如何最大程度获取粒子鉴别能力，是一个关键科学问题。
实际上BESIII四个子探测器都具有一定程度的粒子鉴别能力，但由于不同探测器信息之间的关联十分复杂，传统方法处理起来极其困难，不能获得最佳的粒子鉴别性能。而机器学习方法在解决这种复杂关联问题时具有强大的优势。
因此，我在BESIII实验上利用机器学习方法开展了粒子鉴别的研究。
我选用深度神经网络（DNN）方法，通过参数调试和模型训练，得到适用于BESIII实验𝜋,𝐾,𝑝强子鉴别的机... -

超级陶粲装置（STCF）是中国正在筹划的新一代正负电子对撞机，是研究宇宙中正反物质不对称、探索强子内部结构、寻找奇特态强子和新物理的独特平台。粒子鉴别（PID）作为STCF实验中各种物理研究中最基本的工具之一，对于实现STCF的各种物理目标至关重要。在最近几十年中，机器学习（ML）逐步成为高能物理实验中粒子鉴别的强大替代方法。ML算法，例如神经网络和提升决策树，在处理复杂和多维数据方面表现出卓越性能，所以它们非常适合整合来自多个子探测器系统的粒子鉴别信息。在这项工作中，我们提出了一种基于ML技术的强大PID软件，包括一个全局PID算法用于合并所有子探测器信息实现带电粒子鉴别，以及一个基于量能器响应区分中性粒子的深度CNN算法。初步结果显示基于ML的PID算法取得了出色的粒子鉴别性能，极大地提升了STCF的物理潜力。

基于一整个太阳周期（11年）的AMS数据，我们测量了宇宙线反质子流强随时间的变化，时间粒度27天，刚度范围1-41.9GV。
Go to contribution page
测量结果显示，宇宙线反质子流强具有独特的性质：反质子流强随着刚度增加先升后降，在大约3GV达到最大，而质子、电子、正电子的流强则是一直下降。反质子流强随时间变化的幅度明显比其他粒子要小。反质子和质子流强之间具有变化迟滞关系，而反质子与电子流强之间是线性关系。值得注意的是，在一个11年的太阳周期内，流强随时间变化幅度与流强的能谱形状有明显的相关性。
对于理解宇宙线反质子起源，以及理解太阳调制及其与粒子质量、电荷及能谱形状的关系，AMS的流强随时间的测量结果提供了至关重要的信息。 -

Interest in searches for Charged Lepton Flavor Violation (CLFV) has persisted over the past few decades, as the observation of CLFV would indicate new physics beyond the Standard Model (BSM). Several future high-luminosity lepton colliders have been proposed, which will enable CLFV searches to reach unprecedented precision.

本报告将介绍AMS实验关于宇宙线氘原子核流强和成分测量的最新结果。AMS实验基于收集的2100万宇宙线氘（D）原子核，精确测量了1.9 GV至21 GV刚度范围内的D流强。在整个刚度范围内，D与质子（p）、氦-3（He3）、氦-4（He4）的流强展现出几乎相同的时间变化关系。在4.5 GV以上，D/He4流强比不随时间变化，其刚度依赖性可以用指数为-0.108+/-0.005的单一幂律谱描述。这与He3/He4流强比的幂律谱指数（-0.289+/-0.003）显著不同。在13 GV以上，D与p具有相同的刚度依赖性，D/p流强比为常数0.027+/-0.001。这些现象意味着宇宙线氘核存在初级成分。通过一种模型无关的方式，我们得到初级D成分相当于（9.4+/-0.5）%的He4，次级D成分相当于（58+/-5）%的He3。

We present a pragmatic approach to lower down the mass scale of right-handed neutrinos in leptogenesis by introducing a scalar decaying to right-handed neutrinos.

The neutrino oscillation is described by six independent parameters: three mixing angles $\theta_{23}$, $\theta_{12}$, and $\theta_{13}$), two mass-squared splittings, and one CP-violating phase ($\delta_{\mathrm{cp}}$). As of 2010, only $\theta_{13}$ and $\delta_{\mathrm{cp}}$ remained unknown. However, a non-zero value of $\theta_{13}$ is crucial for exploring CP violation in the lepton...

初级宇宙射线进入大气会与大气分子相互作用产生介子。次级介子在传播过程中有相互竞争的两个过程，衰变为缪子和进一步发生相互作用。大气温度的降低引起的大气分子数密度的减少使得介子和大气分子相互作用的机会减少。有更多的介子衰变而来的缪子产生。因此，地下缪子通量和实验室上方的大气温度有正向的关联，这已被许多实验所观测到。大亚湾实验用两年统计量的数据测量了有效温度和缪子事例率的关联系数。随着大亚湾实验更多数据的获取，期待得到具有更低的统计误差的关联系数。伴随着得到更高水平统计量的数据，有效温度和缪子事例率之间非线性的关联关系被观察到。这一报告将报道大亚湾实验对这一测量的当前的状态。

带电轻子味道破坏（cLFV）过程在标准模型内受中微子质量影响被严重压低，而在多种新物理模型中却可能被提高到实验可观测的量级，因此是新物理模型研究的重要信号之一。考虑到电子缪子相互作用的独特优势，我们研究了未来电子缪子对撞机上由额外引入的中性规范玻色子$Z$'传播的cLFV过程。基于蒙特卡洛计算和检测器快速模拟，我们对cLFV信号和可能的本底的特征进行了研究，并给出了信号在90%置信水平下的截面上限和对应耦合常数$\lambda_{e\mu}$和$\lambda_{e\tau}$的结果。对比当前实验上限与未来实验预期，电子缪子对撞在含陶子末态的耦合常数灵敏度上表现出显著优势。与此同时，轻子对撞实验还可对当前缺乏研究的$\lambda_{\mu\mu}×\lambda_{e\mu}$过程进行测量，且具备较好的灵敏度。

正在我国进行建设的超级陶粲装置（STCF）中需要实现一种全新的、具有较好时间测量能力的电磁量能器（ECAL），以满足背景噪声抑制、中子-γ甄别等物理需求。对时间测量电子学的需求包括：不低于100-ps的分辨率、2-μs以上的动态范围以及可多通道集成。因此，我们提出了一种3级量化结构的时间数字转换器（TDC），其中粗量化由可达到较大动态范围的计数器实现；细量化则是基于一种改进的游标延迟环，利用两种延迟锁相环实现了亚门级延迟的高分辨率。所提出的游标延迟环采用了自动复位机制来实现连续事件的测量，还可利用滑动尺度测量原理显著提高其测量线性度。采用180-nm标准CMOS工艺实现了该TDC原型芯片，共集成了8个测量通道，在100-MHz参考时钟频率下可实现41.7-ps的分辨率和2.56-μs的动态范围。测试结果显示，该TDC的单射精度可达到46.0-ps，DNL不超过0.5-LSB，INL不...

在寻找无中微子双贝塔衰变($0\nu\beta\beta$)的实验中，大部分实验都在限定的RoI范围内使用计数法获取$0\nu\beta\beta$的半衰期灵敏度，也有诸如KamLAND-Zen等实验使用能谱拟合法来完成这一工作，而通过这两种方法获得的$0\nu\beta\beta$半衰期灵敏度存在差异。

本研究基于中国锦屏地下实验室（CJPL）内的本底条件，通过模拟确认了一差异的存在。模拟显示拟合法给出的半衰期灵敏度约为计数法的1.25倍，本研究讨论了这一差异可能的源头。这些结论可以为未来的$0\nu\beta\beta$实验选择数据分析方式提供选择依据。 -

氯化锂水基液闪在作为新型中微子探测器探测介质方面显现出巨大潜力。其中Li-7核素与MeV尺度的太阳中微子发生高截面的带电电流相互作用，为太阳中微子谱的测量提供了可能性。研究团队制备并提纯了一种饱和氯化锂水基液闪，其含盐量为45.3%w/w，并对其光学特性和光产额进行了测量。结果表明，在光电倍增管的敏感波长范围内，该液闪几乎没有吸收。在430 nm波长处的衰减长度可达50米。此外，研究还在氯化锂水基液闪中加入了一种闪烁剂carbostyril-124，并验证了其兼容性和提高光产额的效果，从而促进了切伦科夫增强型富锂探测器的开发。针对这类水基液闪，研究团队还开发了一套重建算法。该算法能够在MeV尺度上重建带电粒子的方向、位置和能量，其中对于4...

直流超导量子干涉仪（DC-SQUID）作为一种低噪声前放，利用磁通锁定的原理线性放大信号，广泛应用于超导边沿探测器（TES）信号的低温读出。为了分析信号，低温放大的信号需要在室温端进一步放大。本工作中，介绍了可以用于TES信号读出的多级串联SQUID阵列（SSA）设计，基于TES读出需求我们设计了一套适用于SSA的低噪声室温读出电子学。室温电子学除了进一步放大读出SSA的低温信号，还为SSA提供磁通反馈回路实现磁通锁定，以及SQUID工作需要的偏置电流、磁通输入信号。我们在4K脉管制冷机中，基于研制的室温电子学提供偏置电流、输入和反馈磁通，实现了磁通锁定放大。我们测试了SSA在不同偏置电流下的超导特性以及磁通响应。得到SQUID临界电流IC、SQUID磁通互感系数M，符合器件设计预期。最后对磁通锁定后系统的噪声成分进行了分析，为下一步系统优化给出了参考。

微结构气体探测器（MPGD）由于其具有高位置分辨、便于大面积制作等优点而得到广泛关注，并逐渐被应用于新一代高能粒子探测实验中。然而，MPGD探测器由于其电荷量较小、收集时间较长以及高颗粒度的特性，对读出电子学性能和集成度提出了新的挑战。同时，鉴于波形数字化技术能够提供最详尽的信息，可根据不同的应用需求选择最佳的信号处理模式。因此，有必要针对MPGD探测器的需求研究新型高精度波形全数字化读出芯片。

在高能物理中，散射振幅连结着理论与实验，扮演着极重要的角色。如何超越传统费曼图，建立新的原理和方法，更好地计算和理解振幅，是振幅现代研究的核心问题之一。在这个报告中，我将给出一种逆用无质量粒子的软行为来构造树图振幅的新方法。这是一种在壳方法，避免了费曼规则的规范冗余度。相比其他逆用软行为的方法，这种新方法不需要假设软因子为已知，只假设软行为的普遍性，因而增大了方法的适用范围，同时也避免了振幅与软因子谁决定谁的逻辑混乱。我将介绍如何用这种方法构造Yang-Mills-scalar与Yang-Mills树图振幅，给出任意点振幅的普遍表达式，并通过double copy结构推广到含引力子的情况。同时，我也会讨论将这种方法推广到有效理论，构造含高阶导数相互作用的胶子振幅，及非线性sigma模型等标量有效理论的振幅。

2023 年 STAR 合作组对重离子碰撞中矢量介子整体自旋排列的测量结果 [1] 表明，碰撞产生的夸克胶子等离子体 (QGP) 中的夸克不仅存在整体极化，还存在整体自旋关联，进而使得对碰撞系统中夸克自旋关联的研究成为了高能自旋物理领域新的增长点。在文献 [2] 中，我们提出了一种系统描述碰撞系统中夸克关联的方法，并证明了矢量介子的矢量极化和两夸克自旋关联之间有紧密联系。进一步地，在文献 [3] 中，我们利用相同的理论框架，发现自旋 3/2 重子的二阶和三阶张量极化，分别依赖于夸克系统中的两夸克和三夸克关联，并且计算了具体的极化分量与相应的夸克自旋关联之间的关系。本报告的主要目的是介绍自旋 3/2 重子张量极化和对应夸克关联之间的关系，以及如何通过测量自旋 3/2 粒子的级联衰变来确定相应的极化分量和夸克的自旋关联。
