Non-perturbative quark mass renormalization in quenched lattice QCD

S Capitani, M Lüscher, R Sommer, H Wittig - Nuclear Physics B, 1999 - Elsevier
The renormalization factor relating the bare to the renormalization group invariant quark
masses is accurately calculated in quenched lattice QCD using a recursive finite-size …

Locality properties of Neuberger's lattice Dirac operator

P Hernandez, K Jansen, M Lüscher - Nuclear Physics B, 1999 - Elsevier
The gauge covariant lattice Dirac operator D which has recently been proposed by
Neuberger satisfies the Ginsparg-Wilson relation and thus preserves chiral symmetry. The …

Renormalization and running of quark mass and field in the regularization invariant and MS schemes at three and four loops

KG Chetyrkin, A Retey - Nuclear Physics B, 2000 - Elsevier
We derive explicit transformation formulae relating the renormalized quark mass and field as
defined in the MS-scheme with the corresponding quantities defined in any other scheme …

Nonperturbatively improved heavy-light mesons: Masses and decay constants

D Becirevic, P Boucaud, JP Leroy, V Lubicz… - Physical Review D, 1999 - APS
We present a study of the heavy-light spectrum and of the D-and B-meson decay constants.
The results were obtained in the quenched approximation, by using the nonperturbatively …

B-parameters of the complete set of matrix elements of (ΔB= 2) operators from the lattice

We study spin 1/2 isoscalar and isovector candidates in both parity channels for the recently
discovered Θ+(1540) pentaquark particle in quenched lattice QCD. Our analysis takes into …

The QCD chiral condensate from the lattice

L Giusti, F Rapuano, M Talevi, A Vladikas - Nuclear Physics B, 1999 - Elsevier
We determine the chiral condensate from simulations of quenched lattice QCD with Wilson
fermions. Our measurements have been obtained with high statistics at three values of the …

Domain decomposition, multilevel integration, and exponential noise reduction in lattice QCD

M Cè, L Giusti, S Schaefer - Physical Review D, 2016 - APS
We explore the possibility of computing fermionic correlators on the lattice by combining a
domain decomposition with a multilevel integration scheme. The quark propagator is …
