Low energy physics from the QCD Schrödinger functional
Joyce Garden, Marco Guagnelli, Jochen Heitger +2
We review recent work by the ALPHA and UKQCD Collaborations where masses and matrix elements were computed in lattice QCD using Schrödinger functional boundary conditions and where…
Hadron masses and matrix elements from the QCD Schr"odinger functional
Marco Guagnelli, Jochen Heitger, Rainer Sommer +1
We explain how masses and matrix elements can be computed in lattice QCD using Schr"odinger functional boundary conditions. Numerical results in the quenched approximation demonstr…
Renormalization group invariant average momentum of non-singlet parton densities
M. Guagnelli, K. Jansen, R. Petronzio
We compute, within the Schrödinger functional scheme, a renormalization group invariant renormalization constant for the first moment of the non-singlet parton distribution functio…
Non-Perturbative Renormalization of Lattice Four-Fermion Operators without Power Subtractions
A. Donini, V. Giménez, G. Martinelli +2
A general non-perturbative analysis of the renormalization properties of four-fermion operators in the framework of lattice regularization with Wilson fermions is presente…
Universal continuum limit of non-perturbative lattice non-singlet moment evolution
M. Guagnelli, K. Jansen, R. Petronzio
We present evidence for the universality of the continuum limit of the scale dependence of the renormalization constant associated with the operator corresponding to the average mo…
