Numerical studies of QCD renormalons in high-order perturbative expansions [PDF]

open access: yes, 2013
Perturbative expansions in four-dimensional non-Abelian gauge theories such as Quantum Chromodynamics (QCD) are expected to be divergent, at best asymptotic. One reason is that it is impossible to strictly exclude from the relevant Feynman diagrams those

LATTICE QCD WITH A CHIRAL TWIST [PDF]

open access: yesPerspectives in Lattice QCD, 2007
In these lectures I explain how chiral symmetry of continuum QCD naturally leads to a class of lattice regularisations known as twisted mass QCD (tmQCD). As compared to standard Wilson quarks, its advantages are the absence of unphysical zero modes, the possibility to circumvent lattice renormalisation problems and automatic O(a) improvement.

Schwinger-Dyson equations in QED and QCD the calculation of fermion-antifermion condensates [PDF]

open access: yes, 2007
We present non-perturbative solutions for the fermion and boson propagators of QED in both three- and four-dimensions, and QCD. In doing so, we solve the coupled system of Schwinger-Dyson equations numerically in Euclidean space, investigating ...

One-loop operator matching in the static heavy and domain-wall light quark system with O(a) improvement

open access: yes, 2011
We discuss perturbative O(g2a) matching with static heavy quarks and domainwall light quarks for lattice operators relevant to B-meson decays and B0–¯B 0 mixing. The chiral symmetry of the light domain-wall quarks does not prohibit operator mixing at O(a)

A Study on the Optimization of Finite Volume Effects of B_K in Lattice QCD

open access: yes, 2015
Lattice quantum chromodynamics (QCD) is the non-perturbative implementation of field theory to solve the QCD theory of quarks and gluons by using the Feynman path integral approach.

Studies of Light Scalar Particles and Dressed Gauge Propagators in QCD [PDF]

open access: yes, 2010
The equations of QCD are widely believed to describe the properties of mesons, baryons and their hadronisation after hard interactions at particle accelerators such as the LHC.

“Improved” computations in lattice QCD

open access: yes, 1991
We present the formalism necessary to reduce the errors due to the finiteness of the lattice spacing from terms of O(a) to terms of O(g02a) in lattice computations of hadronic matrix elements.
