DESCRIPTION:Speakers: 源源 黄 (南京师范大学)\nThe lattice QCD cal
 culation of generalized form factors are exploited to determine the subtra
 ction\nconstants through all order dispersion relations of Deeply Virtual 
 Compton Scattering (DVCS). The\nleading order relation is found to constra
 in significantly the real part of the Compton Form Factors\n(CFFs)\, and t
 he higher order one reduces considerably both the real and imaginary part 
 of CFFs\nin a global analysis of proton data. This is realized by a synthe
 sis of the DVCS data and LQCD\ncalculations within a neural network framew
 ork\, whose architecture is specifically designed for a\nreliable extrapol
 ation to unmeasured kinematic regime. By leveraging dispersion relations b
 eyond\nleading order\, our framework allows for adding higher moments of g
 eneralized parton distributions\nfrom LQCD into the extraction of CFFs fro
 m DVCS data.\n\nhttps://indico.itp.ac.cn/event/437/contributions/2862/

DESCRIPTION:Speakers: 付伟 张 (Inner Mongolia University)\nWe present a
  first-principles lattice QCD calculation of $\\Xi^{-} \\to \\Lambda $ for
 m factors using $2+1$ flavor gauge ensembles with lattice spacings ranging
  from 0.06 to 0.1 fm and pion masses between 230 and 340 MeV. This decay p
 rovides an independent avenue for determining the Cabibbo--Kobayashi--Mask
 awa matrix element $|V_{us}|$ in the baryon sector. We determine the full 
 set of vector and axial-vector transition form factors and their $q^{2}$ d
 ependence\, followed by a combined chiral and continuum extrapolation to t
 he physical point. Our preliminary prediction for the electron-channel bra
 nching fraction is consistent with the recent BESIII measurement\, which l
 ies 3.9 standard deviations below the previous world average.\n\nhttps://i

 D collaboration\, this work performs simultaneous chiral and continuum ext
 rapolations to determine the electromagnetic properties of charmed mesons\
 , providing the first lattice QCD calculations for the magnetic moments an
 d radii of $D^{\\ast+}$ and $D_s^\\ast$\, and filling the gap for the $D_s

DESCRIPTION:Speakers: 世皓 苏 (中国科学院近代物理研究所)\nW
 e investigate the neutral pion transition form factor $F_{\\pi^0\\gamma^\\
 ast\\gamma^\\ast}(q_1^2\,q_2^2)$ in lattice QCD and confirm that the conne
 cted and disconnected contributions\, in the short-distance regime with a 
 fixed time integration\, have the same sign. We employ the recently propos
 ed blending method\, which supplies an unbiased and cheap estimators for t
 he required all-to-all propagators. \nThe external pion states are treated
  within the distillation framework\, while the electromagnetic currents ar
 e evaluated via blending method.  \nNumerical tests are performed on an $N
 _f=2+1$ lattice ensemble. Our result shows that the contribution of the di
 sconnected part is approximately $1\\%$ of that of the connected part and 
 enables constructive interference of probability amplitudes.\n\nhttps://in

DESCRIPTION:Speakers: 川杨 李 (Swansea University)\nSampling algorithms
  for lattice field theories face persistent efficiency challenges near the
  continuum limit\, including critical slowing down and\, in certain fermio
 nic theories\, poor ergodicity across degenerate vacua. Generative diffusi
 on models\, recently shown to correspond to stochastic quantization\, offe
 r a promising alternative and have been demonstrated for scalar and pure g
 auge theories\; their extension to fermionic systems\, central to full QCD
  with dynamical quarks\, has remained largely unexplored.\n\nWe present a 
 diffusion-based sampler for the two-dimensional Gross-Neveu model\, a four
 -fermion lattice theory. The sampler is combined with an exact Monte Carlo
  correction step\, guaranteeing unbiased sampling from the target distribu
 tion. We validate the method in the asymptotically free regime and across 
 the finite-volume crossover\, with observables cross-checked against an in
 dependent reference implementation. This work extends diffusion-based samp
 ling to the fermionic sector and suggests a possible route toward accelera
 ting simulations with dynamical fermions.\n\nhttps://indico.itp.ac.cn/even

DESCRIPTION:Speakers: 啸洋 王 ()\nThe n-point real-time correlation fun
 ction is pivotal for establishing connections between experimental observa
 tions and theoretical predictions using field theories. Conventional metho
 ds for computing n-point correlation functions on quantum computers genera
 lly require an ancilla qubit that controls the entire system -- an approac
 h that poses challenges for digital quantum devices with limited qubit con
 nectivity\, as well as for analog quantum platforms lacking controlled ope
 rations. Here\, we introduce a method to compute n-point correlation funct
 ions using only unitary evolutions on the system of interest\, thereby eli
 minating the need for ancillas and the control operations. We demonstrate 
 our protocol on IBM quantum hardware up to 12 qubits to measure the single
 -particle spectrum of the Schwinger model and the out-of-time-order correl
 ator (OTOC) in the transverse-field Ising model\, where the noiseless simu
 lation results are successfully reproduced from the noisy hardware. Additi
 onally\, I will talk about our recent work on predicting the long-time dyn
 amics of the correlation function from short-time quantum data using Neura
 lODE.\n\nhttps://indico.itp.ac.cn/event/437/contributions/2814/

DESCRIPTION:Speakers: 殿君 赵 (CUHK(SZ))\nExtracting light-cone parton 
 distributions from lattice QCD within Large-Momentum Effective Theory (LaM
 ET) requires a multi-stage data-reduction pipeline: fitting Euclidean corr
 elators for hadronic matrix elements\, renormalizing the resulting matrix 
 elements\, extending and Fourier-transforming them to momentum space\, mat
 ching to light-cone distributions in perturbation theory\, and extrapolati
 ng to the continuum\, infinite-volume\, and physical-mass limits. Several 
 of these stages are procedurally fixed once a scheme is chosen\, but other
 s require a physicist to judge fit windows\, ansatz choices\, and model-av
 eraging strategies from the data itself\, which makes the full pipeline sl
 ow to execute and difficult to reproduce across practitioners. We present 
 \\lamet\, an open-source large language model (LLM) agent framework that f
 ormalizes this pipeline as a declarative\, job-based manifest and exposes 
 each analysis stage as a registry of typed numerical tools. A tool-calling
  LLM loop drives the stages that require strategy selection\, guided by st
 age-local ``skill'' prompts that encode the underlying physics heuristics\
 , while stages that are procedurally fixed run as deterministic tool pipel
 ines. We describe the resulting architecture\, validate the agent-in-the-l
 oop correlator-fitting stage on synthetic two-point-function data\, and ou
 tline its application to an end-to-end pion quasi-parton-distribution-func
 tion (quasi-PDF) workflow in the Coulomb-gauge formulation of LaMET. This 
 paper documents the design and first release\, \\lamet\\ v1.0\, of the fra
 mework.\n\nhttps://indico.itp.ac.cn/event/437/contributions/2763/
