Towards Precision-Controlled Partonic Structures from First Principles
Jinchen He
The internal structure of hadrons is governed by nonperturbative Quantum Chromodynamics (QCD). This dissertation presents first-principles calculations of partonic observables usin…
LaMET-Agent: An Agent Framework for Large-Momentum Effective Theory Analysis
Jinchen He, Xiangyu Jiang, Fei Yao +1
Large-momentum effective theory (LaMET) provides a first-principles framework for computing the dependence of light-cone parton distributions from lattice QCD. Over the past de…
Nucleon Parton Distribution Functions from Boosted Correlations in the Coulomb gauge
Xiang Gao, Jinchen He, Joshua Lin +4
Recently, a novel approach has been proposed to compute parton distributions through the use of boosted correlators fixed in the Coulomb gauge from lattice QCD, within the framewor…
Neural Field Transformations for Hybrid Monte Carlo: Architectural Design and Scaling
Jinchen He, Xiao-Yong Jin, James C. Osborn +1
Critical slowing down, where autocorrelation grows rapidly near the continuum limit due to Hybrid Monte Carlo (HMC) moving through configuration space inefficiently, still challeng…
Probing the Critical Point (CritPt) of AI Reasoning: a Frontier Physics Research Benchmark
Minhui Zhu, Minyang Tian, Xiaocheng Yang +61
While large language models (LLMs) with reasoning capabilities are progressing rapidly on high-school math competitions and coding, can they reason effectively through complex, ope…
Large-Momentum Effective Theory's Asymptotic Extrapolation vs the Inverse Problem
Jiunn-Wei Chen, Xiang Gao, Jinchen He +10
Large-Momentum Effective Theory (LaMET) is a physics-guided systematic expansion to calculate light-cone parton distributions, including collinear (PDFs) and transverse-momentum-de…
Transverse-momentum-dependent pion structures from lattice QCD: Collins-Soper kernel, soft factor, TMDWF, and TMDPDF
Dennis Bollweg, Xiang Gao, Jinchen He +2
We present the first lattice quantum chromodynamics (QCD) calculation of the pion valence-quark transverse-momentum-dependent parton distribution function (TMDPDF) within the frame…
Systematic Uncertainties from Gribov Copies in Lattice Calculation of Parton Distributions in the Coulomb gauge
Xiang Gao, Jinchen He, Rui Zhang +1
Recently, it has been proposed to compute parton distributions from boosted correlators fixed in the Coulomb gauge within the framework of Large-Momentum Effective Theory. This met…
Comments on "Non-local Nucleon Matrix Elements in the Rest Frame"
Xiang Gao, Jinchen He, Yushan Su +2
In a recent paper, "Non-local Nucleon Matrix Elements in the Rest Frame" (Phys. Rev. D 111, 5 (2025)), it was observed that the next-to-leading order calculations of the renormaliz…
