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.

A novel view of the flavor-singlet spectrum from multi-flavor QCD on the lattice

This paper presents a high-statistics lattice study of the flavor-singlet scalar and pseudoscalar spectra in SU(3) gauge theories with 4, 8, and 12 light fermion flavors, contrasting these results with QCD and previous simulations to explore the dynamics of strongly interacting sectors relevant to beyond-the-Standard-Model physics.

Collider Detector Observables from Lattice Spin Systems

This paper proposes using quantum simulation platforms to study collider detector observables by constructing lattice detector operators in spin systems, demonstrating their validity through quantitative agreement with conformal field theory in the 1+1-dimensional quantum Ising model and establishing a pathway for realizing high-energy collider physics on table-top quantum devices.

Nuclear modifications on longitudinal-transverse structure-function ratio RR in the deuteron

This paper challenges the long-held assumption that nuclear modifications do not affect the longitudinal-transverse structure-function ratio RR by demonstrating, through a convolution model of nucleon Fermi motion in the deuteron, that the mixing of longitudinal and transverse components and differing xx-dependencies lead to significant nuclear effects that are currently being investigated experimentally at Jefferson Lab.

Investigating Interacting Fermionic Models with Locality-Preserving Qubit Encodings

This paper demonstrates that combining the locality-preserving Derby-Klassen fermion-to-qubit mapping with a constraint-incorporating Hamiltonian Variational Ansatz enables accurate and resource-efficient quantum simulation of two-dimensional interacting fermionic systems, offering significant advantages over Jordan-Wigner transformations by reducing operator nonlocality and circuit overhead in higher dimensions.

Comment on "Non-Monotonicity of Transverse-Momentum Correlations in Au+Au Collisions at RHIC"

This paper argues that the observed non-monotonic beam-energy dependence of transverse-momentum correlations in Au+Au collisions cannot be reliably attributed to critical phenomena or used to constrain the QCD critical end point due to the absence of a controlled theoretical framework, significant non-critical contributions, and inconsistencies with other susceptibility-based measurements.

On the angular momentum and free energy of rotating gluon plasma

Using first-principle numerical simulations of SU(3) lattice Yang-Mills theory, this study investigates the free energy and angular momentum of rotating hot gluon matter, revealing that both the specific moment of inertia and specific deformation exhibit negative values in the phenomenologically interesting temperature range above the phase transition before turning positive at higher temperatures.
