We compute the hadron mass spectrum, the quark masses, and the meson decay constants in quenched lattice QCD with nonperturbatively $O(a)$-improved Wilson fermions. The calculations are done for two… Continue Reading
We present a study of the SU(3) glueball spectrum for all JPC values at lattice spacings down to a−1 = 3.73(6) GeV (β = 6.4) using lattices of size up to 324. We extend previous studies and show that… Continue Reading
Abstract About half the mass of a hadron is given from gluonic contributions. In this talk we calculate the chromoelectric and chromo-magnetic components of the nucleon mass. These computations are… Continue Reading
We report on preliminary results of a high statistics quenched lattice QCD calculation of nucleon matrix elements within the Symanzik improvement programme. Using the recently determined… Continue Reading
We present first results for light hadron masses, quark masses and decay constants in the continuum limit using O(a) improved fermions at three different values of the gauge coupling β.
We present initial results for light hadron masses and nucleon structure functions using a recent proposal for eliminating all O(a) effects from Wilson fermion simulations in the quenched… Continue Reading
Abstract Continuing our investigations of quenched QCD with improved fermions we have started simulations for lattice size 32 3 × 64 at β = 6.2. We present first results for light hadron masses at κ… Continue Reading
The renormalisation constants for local bilinear quark operators are calculated using the Sheikholeslami-Wohlert improved action. In addition we compute the renormalisation constant of the leading… Continue Reading
Abstract Within the framework of lattice QCD a high statistics computation of the nucleon axial and tensor charges is given. Particular attention is paid to the chiral and continuum extrapolations.
We review the status of lattice calculations of the deep-inelastic structure functions of the nucleon. In addition, we present some results on the pion and rho structure functions.
