格点 QCD 为研究强相互作用非微扰性质提供了第一性原理方法，但从物理问题到实际数值计算通常涉及关联函数构造、Wick 收缩、传播子求解、程序实现以及高性能计算等一系列复杂流程。LQCDMaster 面向这一问题，构建了融合大语言模型、格点 QCD 专业知识与确定性计算工具的科研智能体，将自然语言研究需求自动转化为物理方案、可执行的 PyQUDA 程序和 HPC 计算任务，并对关键步骤进行验证。本报告将介绍 LQCDMaster 的基本架构及其在强子谱、多强子体系、形状因子和非定域关联函数等问题中的应用，并讨论科研智能体如何降低格点 QCD 的工程门槛，推动从 AI Agent 向自主科学研究工作流的发展。

850. Can we observe the Higgs self-coupling with Run 2+3 data? – Going jet-free

Congqiao Li

"Searching for Higgs pair production and precisely measuring the Higgs self-coupling modifier $\kappa_\lambda$ are among the key milestones for the next stage of the LHC programme. In Ref. [1], we demonstrated that, in the HH→4b channel, a “jet-free” approach can achieve a surprisingly large >5× improvement in sensitivity, potentially bringing observation-level sensitivity to Higgs pair...

851. Reconstructing the Invisible Fraction of Semi-visible Jets in ISR-Boosted Events via Neural Network Regression

"Semi-visible jets (SVJs) provide a characteristic collider signature of strongly interacting dark sectors, in which the key model parameter rinv controls the fraction of dark hadrons decaying to dark matter candidates. Dedicated searches for SVJs have been performed at the LHC. Both CMS and ATLAS have probed resonant s-channel SVJ production and set constraints on the corresponding signal...

852. Reinterpretaion of pMSSM based on Active Learning

Zihang Liu

"The Standard Model (SM) describes the known elementary particles with high precision, yet it does not explain the origin of the electroweak scale, incorporate gravity, or provide a dark-matter candidate — shortcomings motivating the search for physics beyond the Standard Model (BSM). Supersymmetry (SUSY) is a leading BSM candidate; in its gauge-mediated supersymmetry breaking (GMSB) branch,...

853. Boosted bb/cc/tautau calibration ATLAS

段宗欢

This presentation provides an overview of the Transformer-based GN3X boosted jet tagger in ATLAS, focusing on its performance and calibration for bb, cc, and tautau identification.

854. SWDSIM: Fast and Accurate Simulation of Resolution Effects Using Sliced Wasserstein Distance

潘楚铖

31/10/2026, 15:30

We present SWDSIM, a fast-simulation approach for modelling detector-resolution effects using the Sliced Wasserstein Distance (SWD). The method learns the mapping from generator-level to fully simulated kinematics using existing simulated samples and can be transferred to other decay channels with same final-state. We will introduce the method and its implementation, present validation studies...
