3-point functions from twisted mass lattice QCD at small quark masses
S. Capitani, K. Jansen, M. Papinutto +3
We show at the example of the matrix element between pion states of a twist-2, non-singlet operator that Wilson twisted mass fermions allow to compute this phenomenologically relev…
Pion form factor with chirally improved fermions
Stefano Capitani, Christof Gattringer, C. B. Lang
We present results for Monte Carlo calculations of the electromagnetic vector and scalar form factors of the pion in a quenched simulation. We work at a lattice spacing of 0.15 fm…
Status of lattice structure function calculations
Stefano Capitani
Lattice QCD allows computations of moments of structure functions from first principles. An overview of the present status of the calculations is given. Recent results and future p…
Perturbative renormalization for overlap fermions
Stefano Capitani
Using lattice overlap fermions, we have computed the 1-loop renormalization factors of several operators that measure DIS structure functions and weak amplitudes. Computer codes wr…
Improvement for Quenched Wilson Fermions
S. Capitani, M. Goeckeler, R. Horsley +9
We briefly describe some of our recent results for the mass spectrum and matrix elements using improved fermions for quenched QCD. Where possible a comparison is made betwee…
Local bilinear operators on the lattice and their perturbative renormalisation including O(a) effects
S. Capitani, M. Göckeler, R. Horsley +4
Some basic concepts are discussed to derive renormalisation factors of local lattice operators relevant to deep inelastic structure functions and to other measurable quantities. Th…
