Consistency between Lüscher’s finite volume method and HAL QCD method for two-baryon systems in lattice QCD

open access: yesJournal 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 ...

Relativistic-invariant formulation of the NREFT three-particle quantization condition

open access: yesJournal of High Energy Physics, 2022
A three-particle quantization condition on the lattice is written down in a manifestly relativistic-invariant form by using a generalization of the non-relativistic effective field theory (NREFT) approach.

Towards Novel Insights in Lattice Field Theory with Explainable Machine Learning [PDF]

open access: yesPhysical Review D, 2020
Machine learning has the potential to aid our understanding of phase structures in lattice quantum field theories through the statistical analysis of Monte Carlo samples. Available algorithms, in particular those based on deep learning, often demonstrate

On the three-particle analog of the Lellouch-Lüscher formula

open access: yesJournal 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,

Radial lattice quantization of 3D ϕ4 field theory [PDF]

open access: yesPhysical Review D, 2020
The quantum extension of classical finite elements, referred to as quantum finite elements ({\bf QFE})~\cite{Brower:2018szu,Brower:2016vsl}, is applied to the radial quantization of 3d $\phi^4$ theory on a simplicial lattice for the $\mathbb R \times ...

Tensor polarizability of the vector mesons from SU(3) lattice gauge theory

open access: yesJournal of High Energy Physics, 2018
The magnetic dipole polarizabilities of the vector ρ 0 and ρ ± mesons in SU(3) pure gauge theory are calculated in the article. Based on this the authors explore the contribution of the dipole magnetic polarizabilities to the tensor polarization of the ...

Isospin breaking corrections to meson masses and the hadronic vacuum polarization: a comparative study

open access: yesJournal 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 =

Lattice Wess-Zumino-Witten Model and Quantum Groups [PDF]

open access: yes, 1992
Quantum groups play a role of symmetries of integrable theories in two dimensions. They may be detected on the classical level as Poisson-Lie symmetries of the corresponding phase spaces.
