Journal of High Energy Physics, 2017 We calculate the strong isospin breaking and QED corrections to meson masses and the hadronic vacuum polarization in an exploratory study on a 64 × 243 lattice with an inverse lattice spacing of a −1 = 1.78 GeV and an isospin symmetric pion mass of m π =

On the three-particle analog of the Lellouch-Lüscher formula
Journal of High Energy Physics, 2021 Using non-relativistic effective field theory, we derive a three-particle analog of the Lellouch-Lüscher formula at the leading order. This formula relates the three-particle decay amplitudes in a finite volume with their infinite-volume counterparts and,

Simulating thimble regularization of lattice quantum field theories [PDF]
Proceedings of 34th annual International Symposium on Lattice Field Theory — PoS(LATTICE2016), 2017 Monte Carlo simulations of lattice quantum field theories on Lefschetz thimbles are non trivial. We discuss a new Monte Carlo algorithm based on the idea of computing contributions to the functional integral which come from complete flow lines. The latter are the steepest ascent paths attached to critical points, i.e.

Topological Interpretations of Lattice Gauge Field Theory [PDF]
, 1997 We construct lattice gauge field theory based on a quantum group on a lattice of dimension 1. Innovations include a coalgebra structure on the connections, and an investigation of connections that are not distinguishable by observables.

Induced QCD II: numerical results
Journal of High Energy Physics, 2019 We numerically explore an alternative discretization of continuum SU(N c ) Yang-Mills theory on a Euclidean spacetime lattice, originally introduced by Budzcies and Zirnbauer for gauge group U(N c ).

Thermal QCD in a non-uniform magnetic background
Journal of High Energy Physics, 2023 Off-central heavy-ion collisions are known to feature magnetic fields with magnitudes and characteristic gradients corresponding to the scale of the strong interactions.

Journal of High Energy Physics, 2019 There exist two methods to study two-baryon systems in lattice QCD: the direct method which extracts eigenenergies from the plateaux of the temporal correlation function and the HAL QCD method which extracts observables from the non-local potential ...

N $$ \mathcal{N} $$ = 1 Super-Yang-Mills theory on the lattice with twisted mass fermions
Journal of High Energy Physics, 2021 Super-Yang-Mills theory (SYM) is a central building block for supersymmetric extensions of the Standard Model of particle physics. Whereas the weakly coupled subsector of the latter can be treated within a perturbative setting, the strongly coupled ...

Review of lattice studies of resonances [PDF]
, 2012 I review recent progress in extracting resonance parameters using lattice field theory, with an emphasis on determining hadron resonances from lattice quantum chromodynamics.

A single-particle framework for unitary lattice gauge theory in discrete time
New Journal of Physics, 2022 We construct a real-time lattice-gauge-theory (LGT)-type action for a spin-1/2 matter field of a single particle on a $(1+1)$ -dimensional spacetime lattice.
