This paper proposes a string field theory for branched polymers with loops coupled to the critical Ising model, demonstrating that its non-perturbative partition function satisfies a third-order linear differential equation and a Wheeler-DeWitt equation derived via both matrix model loop equations and stochastic quantization.
This paper conjectures a lower bound for the critical exponent in continuous phase transitions described by Landau-Ginzburg-Wilson theories, proposing the inequality (which implies for unitary theories) based on the condition , a hypothesis supported by arguments from lattice models, -expansions, and exact two-dimensional conformal field theory results.
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.
This paper presents a first-principles lattice QCD calculation of the proton-proton fusion matrix element at an unphysical pion mass, demonstrating the feasibility of the approach while highlighting that large uncertainties in two-nucleon scattering parameters currently limit the precision of the extracted low-energy constant .
This paper presents a study of the mass spectra and mass differences of heavy hadrons containing bottom quarks using MILC's 2+1+1 flavor HISQ gauge ensembles, employing a mixed-action approach with NRQCD for bottom quarks, anisotropic Clover for charm, and O(a)-improved Wilson-Clover for light and strange quarks.
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 non-perturbative determination of the QCD Equation of State for three massless quark flavors across a temperature range from 3 GeV to the electroweak scale, revealing that even at these extreme temperatures, perturbative predictions remain insufficient without incorporating non-perturbative contributions.
Using a unified chiral effective field theory framework calibrated with lattice QCD data, this study predicts repulsive interactions for the system while identifying strong attractive forces in the system that support bound states, with significant mass splitting between channels driven by two-pion exchange spin-spin terms.
This paper proposes and numerically verifies a lattice formulation of the -valued Arf-Brown-Kervaire invariant for Majorana fermions on two-dimensional non-oriented manifolds, demonstrating that it can be extracted from Pfaffians of the Wilson Dirac operator and agrees with continuum theory results.
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.
This paper presents a one-loop computation of the quark propagator in the Curci-Ferrari-Delbourgo-Jarvis gauge with dynamical quarks, demonstrating that the framework remains infrared-stable with frozen coupling and mass parameters, while suggesting that finite gauge parameters may better align with lattice trends than the Landau gauge.
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 $3\pi2\pi$ systems.
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 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 demonstrates how to extract baryon light-front wave functions from equal-time lattice QCD correlators by proving their factorization into a three-quark color-singlet component, a residual lattice factor, and a soft factor, while also verifying the wave function's renormalizability and deriving its evolution equations.
Using tensor network simulations on a $24 \times 24$ 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 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.
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.
This Letter presents an improved, model-independent calculation of radiative corrections to decays that incorporates structure-dependent effects beyond point-like pions and threshold enhancements, thereby refining the precision of the hadronic-vacuum-polarization contribution to the muon's anomalous magnetic moment derived from tau decay data.
This study demonstrates the first observation of robust, coherent non-Abelian hadron dynamics on a noisy 156-qubit quantum processor by simulating a 60-site SU(2) lattice gauge theory using a hardware-efficient encoding, successfully capturing meson propagation and breathing modes while outperforming classical approximation methods in the weak-coupling regime.
