More on the flavor dependence of m ϱ /f π

open access: yesJournal of High Energy Physics, 2021
In previous work, [ arXiv:1905.01909 ], we have calculated the m ϱ /fπ ratio in the chiral and continuum limit for SU(3) gauge theory coupled to N f = 2, 3, 4, 5, 6 fermions in the fundamental representation.

Implementing the three-particle quantization condition for π + π + K + and related systems

open access: yesJournal of High Energy Physics, 2022
Recently, the formalism needed to relate the finite-volume spectrum of systems of nondegenerate spinless particles has been derived. In this work we discuss a range of issues that arise when implementing this formalism in practice, provide further ...

The continuum and leading twist limits of parton distribution functions in lattice QCD

open access: yesJournal of High Energy Physics, 2021
In this study, we present continuum limit results for the unpolarized parton distribution function of the nucleon computed in lattice QCD. This study is the first continuum limit using the pseudo-PDF approach with Short Distance Factorization for ...

fcc lattice, checkerboards, fractons, and quantum field theory [PDF]

open access: yesPhysical Review B, 2021
We consider XY-spin degrees of freedom on an fcc lattice, such that the system respects some subsystem global symmetry. We then gauge this global symmetry and study the corresponding $U(1)$ gauge theory on the fcc lattice. Surprisingly, this $U(1)$ gauge theory is dual to the original spin system.

Relativistic N-particle energy shift in finite volume

open access: yesJournal of High Energy Physics, 2021
We present a general method for deriving the energy shift of an interacting system of N spinless particles in a finite volume. To this end, we use the nonrelativistic effective field theory (NREFT), and match the pertinent low-energy constants to 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 =

Induced QCD II: numerical results

open access: yesJournal 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 ).

Critical 1- and 2-point spin correlations for the O(2) model in 3d bounded domains

open access: yesJournal of High Energy Physics, 2021
We study the critical properties of the 3d O(2) universality class in bounded domains through Monte Carlo simulations of the clock model. We use an improved version of the latter, chosen to minimize finite-size corrections at criticality, with 8 ...

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 ...
