The chirally rotated Schrödinger functional: theoretical expectations and perturbative tests

open access: yesJournal of High Energy Physics, 2016
The chirally rotated Schrödinger functional (χSF) with massless Wilson-type fermions provides an alternative lattice regularization of the Schrödinger functional (SF), with different lattice symmetries and a common continuum limit expected from ...

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.

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,

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 ...

Thermal QCD in a non-uniform magnetic background

open access: yesJournal 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.

Quantum simulation of the (1+1)-dimensionalU(1)Lattice QED with Rydberg atoms [PDF]

open access: yes, 2022
Gauge Theories like Quantum chromodynamics (QCD) display non perturbative effects which mostlyprevent their study via analytical tools. A possible approach to study and simulate these theoriesis the Lattice Gauge Theory formulation, i.e., a space-time ...

N $$ \mathcal{N} $$ = 1 Super-Yang-Mills theory on the lattice with twisted mass fermions

open access: yesJournal 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 ...

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 =
