Update on ɛK with lattice QCD inputs
EPJ Web of Conferences, 2018 We report updated results for ɛK, the indirect CP violation parameter in neutral kaons, which is evaluated directly from the standard model with lattice QCD inputs. We use lattice QCD inputs to fix B⌢K,Vcb,ξ0,ξ2,Vus, and mc(mc).

Lattice QCD in Rotating Frames [PDF]
Physical Review Letters, 2013 We formulate lattice QCD in rotating frames to study the physics of QCD matter under rotation. We construct the lattice QCD action with the rotational metric and apply it to the Monte Carlo simulation. As the first application, we calculate the angular momenta of gluons and quarks in the rotating QCD vacuum.

Lattice Quantum ChromoDynamics with approximately chiral fermions [PDF]
, 2008 In this work we present Lattice QCD results obtained by approximately chiral fermions. We use the CI fermions in the quenched approximation to investigate the excited baryon spectrum and to search for the Theta^+ pentaquark on the lattice. Furthermore we

Odd-spin glueballs, AdS/QCD and information entropy
Physics Letters B, 2020 Odd-spin glueballs in the dynamical AdS/QCD model are scrutinized, in the paradigm of the configurational entropy (CE). Configurational-entropic Regge trajectories, that relate the CE underlying odd-spin glueballs to their mass spectra and spin, are then

Strangeness in lattice QCD [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2001 The status of lattice calculations in the light hadron sector is reviewed. Special emphasis is given to recent lattice determinations of the mass of the strange quark. The impact of non-perturbative renormalization and control over lattice artefacts on the attainable precision is discussed in detail. Furthermore the influence of dynamical quark effects

Vacuum correlators at short distances from lattice QCD
Journal of High Energy Physics, 2021 Non-perturbatively computing the hadronic vacuum polarization at large photon virtualities and making contact with perturbation theory enables a precision determination of the electromagnetic coupling at the Z pole, which enters global electroweak fits ...

Multigrid deflation for Lattice QCD
Journal of Computational Physics, 2020 Computing the trace of the inverse of large matrices is typically addressed through statistical methods. Deflating out the lowest eigenvectors or singular vectors of the matrix reduces the variance of the trace estimator. This work summarizes our efforts to reduce the computational cost of computing the deflation space while achieving the desired ...
