hep-lat papers | Gist.Science

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.

Real-time Estimators for Scattering Observables: A full account of finite volume errors for quantum simulation

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.

Heavy quark masses from step-scaling

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.

Quantum State Preparation with Resolution Refinement

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.

Towards four-pion effects in multi-hadron decays

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.

$B \to \pi$ , $B_{(s)} \to D_{(s)}$ from 2+1+1 Flavor Lattice QCD

This paper presents a 2+1+1-flavor lattice QCD calculation of hadronic form factors for $B \to \pi$ and $B_{(s)} \to D_{(s)}$ 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 $|V_{cb}|$ .

Thermalization of SU(2) Lattice Gauge Fields on Quantum Computers

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.

Chiral Anomaly of Kogut-Susskind Fermion in the (3+1)-dimensional Hamiltonian formalism

This paper investigates the chiral anomaly of Kogut-Susskind fermions in a (3+1)-dimensional Hamiltonian formalism by defining a non-onsite axial charge that, while generally non-conserved, satisfies the continuum anomalous conservation law for specific $U(1)$ link configurations, as confirmed by numerical simulations.

Phase structure of heavy dense lattice QCD and three-state Potts model

By mapping the high-density heavy-quark limit of QCD to a three-dimensional three-state Potts model with a complex external field, the study reveals that the finite-temperature phase transition evolves from first-order to crossover and back to first-order as density increases, strongly suggesting a first-order transition persists in the high-density heavy-quark region of QCD.

Preparing Fermions via Classical Sampling and Linear Combinations of Unitaries

This paper presents an extension of the Evolving density matrices on Qubits (E $\rho$ OQ) framework that overcomes the fermionic sign problem by combining classical stochastic sampling with linear combinations of unitaries, enabling efficient fault-tolerant preparation of fermionic states with $\mathcal{O}(M^2)$ circuit complexity and validated through simulations of the Thirring model.
