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.

This paper investigates the phase diagram of 4D SU(3) Yang-Mills theory at by simulating the theory with an imaginary theta parameter and performing analytic continuation to address the sign problem, utilizing stout smearing and reweighting techniques to confirm the spontaneous breaking and subsequent restoration of CP symmetry at the deconfining temperature.
Based on recent lattice evidence and 't Hooft anomaly constraints, this paper proposes that the chiral phase transition in hot QCD for massless flavors may be described by a conformal manifold of -dependent universality classes featuring an exactly marginal operator related to baryon density, rather than a standard Ginzburg-Landau critical point.
This paper presents a hybrid quantum-classical algorithm utilizing a universal Euler-Cartan parametrized circuit ansatz to efficiently compute non-perturbative characteristics, such as energy spectra and excitation states, of quantum field theories on lattice realizations with both short and long-range interactions.
Using tensor network simulations on a lattice, this study characterizes the scattering dynamics of bound states and resonances in the two-dimensional quantum Ising model and demonstrates that highly-energetic collisions can induce violent false vacuum decay, leading to the spread of true vacuum bubbles.
This paper investigates the two-body nonleptonic decays of into accompanied by pseudoscalar or vector mesons using the naive factorization approach, calculating decay amplitudes across various topologies to determine rates and branching ratios for comparison with other theoretical predictions and experimental data.
Using (2+1)-flavor lattice QCD at the physical point, this study calculates the S-wave - interaction potentials via the HAL QCD method, revealing overall attraction in both spin channels that precludes the formation of a dibaryon bound state and highlighting the dominant role of spin-independent forces driven by heavy-hadron chromo-polarizability.
This paper presents the first sub-percent precision lattice QCD calculation of the next-to-leading order hadronic vacuum polarization contribution to the muon anomalous magnetic moment, yielding a result of that is twice as precise as the 2025 White Paper estimate and shows a significant 4.8 tension with data-driven evaluations excluding the CMD-3 measurement.
This paper summarizes how derivatives of the QCD pressure calculated via lattice QCD are used to construct observables that probe the QCD phase diagram at physical quark masses, specifically analyzing the -flavor chiral phase transition, deconfinement, and the convergence properties of Taylor expansions in the search for the critical endpoint.
This paper introduces a nonperturbative Hamiltonian framework that rigorously connects finite-volume lattice QCD spectra to experimental scattering observables, successfully demonstrating its utility by extracting robust resonance parameters for the meson through a unified analysis of coupled and systems.
This paper argues that in interacting quantum field theories at finite density, the derivative of entanglement entropy with respect to subregion size converges to the thermal entropy density in the large-subregion limit, thereby establishing a universal link between entanglement and thermodynamics that allows for the extraction of equation-of-state information, as demonstrated nonperturbatively in the three-dimensional O(4) model.
