Hep-Lat, short for High Energy Physics – Lattice, explores the fundamental forces of nature by simulating particle interactions on a digital grid. Instead of relying solely on abstract equations, researchers in this field use powerful computers to model how quarks and gluons bind together, offering deep insights into the structure of matter that are often impossible to derive analytically.
Gist.Science ensures these complex discoveries from arXiv remain accessible to everyone. We process every new preprint in this category as it is posted, providing both plain-language explanations for the curious and detailed technical summaries for experts. This dual approach bridges the gap between cutting-edge simulation work and broader scientific understanding.
Below are the latest papers in High Energy Physics – Lattice, curated directly from arXiv and ready for you to explore.
This paper utilizes unique scaling function properties and an improved chiral order parameter to directly estimate the chiral phase transition temperature and universal critical parameters from (2+1)-flavor QCD simulations, while quantitatively analyzing finite-volume effects and deviations from universal scaling as a function of the light-to-strange quark mass ratio.
This paper introduces a domain decomposition-based subtraction method that significantly reduces the statistical noise of disconnected diagrams in full QCD by achieving a three-order-of-magnitude variance reduction at a modest computational cost, offering a practical alternative to neglecting these contributions.
This paper presents preliminary results from the first extensive study of Sp(4) lattice gauge theory using Möbius domain wall fermions, demonstrating that optimized parameter choices effectively suppress lattice artifacts and enable reliable continuum-limit extrapolations for composite Higgs and dark matter models.
This study demonstrates that the ferromagnetic Ising model on finite hyperbolic lattices exhibits distinct universality classes dependent on boundary conditions, where open boundaries yield a new critical behavior with non-mean-field exponents while wired boundaries recover standard mean-field criticality.
This paper introduces ScoreNF, a score-based normalizing flow framework integrated with an Independent Metropolis-Hastings module that enables efficient, unbiased sampling from unnormalized distributions using small training ensembles, thereby overcoming the limitations of traditional MCMC and data-hungry machine learning models.
This paper reports the first implementation of Real-time Estimators for Scattering Observables (RESOs) on IBM quantum hardware, successfully computing spacetime correlation functions for a 1D fermion lattice model using 109 qubits to demonstrate the extraction of bound states and scattering amplitudes.
This paper introduces LaMET-Agent, an open-source large language model framework that automates and standardizes the complex, multi-stage workflow of Large-Momentum Effective Theory analysis for computing light-cone parton distributions from lattice QCD, successfully validating its capabilities across multiple pion and kaon distribution studies.
The paper introduces SIMANF, a sample-free framework that combines simulated annealing with normalizing flows to effectively learn and sample from high-dimensional, multimodal unnormalized distributions by progressively transforming the target density and transferring representations across stages to prevent mode collapse.
The paper introduces FUND, a novel algorithm that learns Boltzmann distributions without requiring true training samples by iteratively reshaping the target distribution through distribution-trajectory matching, thereby overcoming the limitations of MCMC and existing flow-based methods in terms of efficiency, ergodicity, and mode coverage.
This paper presents preliminary results on baryon mass splittings within spin-1/2 and spin-3/2 SU(2) multiplets, calculated using the RM123 method on twisted-mass lattice ensembles near physical quark masses to incorporate leading-order isospin-breaking corrections from electromagnetic interactions and the up-down quark mass difference.
