Summary: The YM theory has been generalized to 2YM and 3YM theories, and similarly, the BFYM theory has been generalized to 2BFYM and 3BFYM theories. It is shown that these higher BFYM theories can provide formulations for the corresponding higher form YM theories. Additionally, the gauge symmetries of these higher BFYM theories are also studied.

Summary: We study lattice fermions using spectral graph theory (SGT). We find that a fermion on a lattice can be understood as a spectral graph. SGT helps in determining the number of fermion species on lattices with arbitrary topologies by investigating the zero eigenvalues of lattice Dirac operators. We apply the procedure of SGT to various lattice fermion formulations and reproduce the known results on the number of species.

Summary: This study proposes to use noisy-intermediate-scale-quantum-era quantum devices to compute short distance quantities in (2 + 1)-dimensional QED, and combine them with large volume Monte Carlo simulations and perturbation theory. By performing quantum computations, the mass gap in the small and intermediate regime can be reliably resolved and matched with corresponding results from Monte Carlo simulations.

Summary: The article introduces the lattice compact Abelian Higgs model and quantum simulation using a ladder-shaped optical lattice in 1 + 1 dimensions. By building local Hilbert spaces with Rydberg atoms, the concept of ladder-shaped configurable arrays is proposed. Concrete proposals involving two and three atoms for constructing spin-1 spaces and analytical tools for design and building are discussed.

Summary: The Landau-gauge quark propagator is calculated and analyzed using overlap valence fermions on 2+1-flavour dynamical clover fermion gauge fields from the PACS-CS collaboration. The obtained mass and renormalization functions are examined and compared with results from O(a)-improved Wilson fermions on 2-flavour dynamical gauge fields.

Summary: In this study, we designed a protocol for digital quantum computation of a gauge theory with a topological term in Minkowski spacetime. We focused on the 1+1 dimensional quantum electrodynamics with the Schwinger model and tested our protocol on an IBM simulator. By constructing the true vacuum state using adiabatic state preparation, we were able to compute the expectation value of the fermion mass operator and compare our results with the known exact result in the massless case. Although there were deviations in the massive case, our results imply that digital quantum simulation is a promising tool to explore nonperturbative aspects of gauge theories with real time and topological terms.

Summary: Through non-relativistic effective field theory, a three-particle analog of the Lellouch-Luscher formula at the leading order has been derived. This formula establishes a connection between three-particle decay amplitudes in a finite volume and their infinite-volume counterparts, making it applicable for lattice studies on three-particle decays. The potential generalization of this approach to higher orders has also been briefly discussed.

Summary: In this paper, a three-particle quantization condition on the lattice is formulated in a manifestly relativistic-invariant form using a generalization of the non-relativistic effective field theory (NREFT) approach. The inclusion of higher partial waves is explicitly addressed, and the quantization condition is partially diagonalized into irreducible representations of the octahedral group in both the center-of-mass frame and moving frames. By generating synthetic data in a toy model, the relativistic invariance of the three-body bound state spectrum is explicitly demonstrated.

Summary: This approach utilizes measurement-based quantum computation principles, involving entangled resource states and local measurements, and presents two measurement-based VQE schemes, introducing a new method for constructing variational families and translating circuit-based schemes. Both schemes offer specific advantages in terms of required resources and coherence times.

Summary: The study introduces a scalable analog quantum simulator for quantum electrodynamics in two dimensions, using ultracold atomic mixtures in an optical lattice. By engineering spatial plaquette terms for magnetic fields, a major obstacle towards realizing realistic gauge theories in higher dimensions is solved. The phenomenon of confinement of electric charges is discussed in the context of the pure gauge theory of compact QED within this quantum simulator.

Summary: In this study, the masses, decay constants, and anomalous matrix elements of the eta and eta ' mesons in N-f = 2 + 1 QCD were determined using non-perturbatively improved Wilson fermions. The data are consistent with Chiral Perturbation Theory (ChPT) and give insights into the quark mass dependence, singlet axial Ward identity, and gluonic matrix elements.

Summary: The method discussed in the paper presents a way to construct hadronic scattering and decay amplitudes from Euclidean correlators by combining inverse Laplace transform and the work of Maiani and Testa. By inserting a smooth step function in the spectral decomposition, the large t limit can project onto scattering or decay amplitudes above threshold. The utility of this method is highlighted through large t expansions of both three- and four-point functions, showing improved convergence compared to the expansion in powers of 1/t.

Summary: Observables in particle physics, particularly in lattice QCD calculations, are often obtained through fits. However, reliable determination of the covariance matrix and its inverse from correlated and auto-correlated data is challenging and can lead to close-to-singular estimates. To address this, modifications of the X2 definition, such as uncorrelated fits, are proposed. We demonstrate how the goodness-of-fit measured by the p-value can still be robustly estimated for a wide range of such fits.

Summary: In this study, we calculate shear viscosity and bulk viscosity in SU(3) gauge theory on the lattice at 1.5Tc. The viscosities are extracted via a Kubo formula from the reconstructed spectral function and the analysis of energy-momentum tensor correlators. We achieve unprecedented precision by applying gradient-flow and blocking methods, and obtain final estimates for shear and bulk viscosity.

Summary: In this study, we investigated the properties of diquarks on a lattice in the presence of a static quark. The results show the mass differences between different diquark channels, as well as the differences in mass between diquarks and quarks. The lightest and next-to-lightest diquarks have good scalar and bad axial vector quantum numbers, with a significant mass difference for ud flavors. Additionally, we found that the attraction between quarks is only present in certain diquark channels. The size of the corresponding diquark is estimated to be around 0.6 fm, and its shape is determined to be spherical. These findings provide quantitative support for modeling the low-lying baryon spectrum using effective degrees of freedom of light diquarks.

Summary: Phase shifts for s-wave MM scattering in both the I = 0 and I = 2 channels are determined from lattice QCD calculations, supporting the study of direct CP violation in K -> pi pi decay. Various techniques are used to refine the results and analyze systematic errors, with comparisons made to the generalized eigenvalue problem method.
