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.
Using high-statistics lattice QCD simulations with twisted mass fermions at physical quark masses, the authors determine non-zero nucleon strange electromagnetic form factors and radii in the continuum limit while finding the charm electromagnetic form factors consistent with zero.
This paper presents the first continuum-limit calculation of nucleon strange electromagnetic form factors using lattice QCD simulations with physical quark masses, yielding results with statistical and systematic uncertainties an order of magnitude smaller than current experimental determinations.
This paper presents an updated determination of light and strange quark masses in QCD with dynamical flavors using -improved Wilson fermions on CLS ensembles, featuring non-perturbative renormalization and a controlled extrapolation to the physical point across five lattice spacings.
This paper establishes that real-time estimators for scattering observables in gapped quantum field theories are universally applicable and yield exponentially suppressed finite-volume errors through complex spectral displacement and boost averaging, thereby enabling the quantum simulation of previously inaccessible scattering phenomena relevant to hadron physics and Standard Model precision tests.
This paper proposes using configurational temperature as a robust, physically interpretable diagnostic tool to verify the thermodynamic consistency and reliability of Complex Langevin simulations, effectively detecting algorithmic errors and ensuring accurate results in systems plagued by the sign problem.
This paper presents a precise determination of charm and bottom quark masses using a heavy-quark step-scaling strategy that connects small-volume relativistic simulations to large-volume CLS ensembles, offering a complementary approach with distinct systematic uncertainties to standard large-volume methods.
This paper introduces "resolution refinement," an efficient method for bootstrapping quantum eigenstate preparation by adiabatically evolving states from low-resolution to high-resolution Hamiltonians, achieving favorable scaling with system size by preserving the structure of low-energy eigenstates.
This paper presents a new perturbative formalism that relates finite-volume energies and matrix elements to infinite-volume couplings for systems involving up to four pions, enabling the numerical study of volume-dependent spectra and the quantification of four-particle effects in multi-hadron decays.
This paper presents a 2+1+1-flavor lattice QCD calculation of hadronic form factors for and semileptonic decays using highly improved staggered quarks on MILC ensembles, aiming for a percent-level determination of these form factors to enable high-precision measurements of .
This paper demonstrates the feasibility of simulating the thermalization dynamics of minimally truncated SU(2) lattice gauge theory on current noisy quantum hardware by successfully matching error-mitigated results from IBM quantum computers with classical simulations for chains of up to 101 plaquettes.
