Four-quark operators in hadrons
S. Capitani, M. Gockeler, R. Horsley +8
We present calculations of matrix elements of 4-quark operators in the pion and in the nucleon extracted from quenched Monte Carlo simulations at beta = 6.0 using Wilson fermions.…
Quenched QCD near the chiral limit
M. Gockeler, R. Horsley, D. Petters +3
A numerical study of quenched QCD for light quarks is presented using O(a) improved fermions. Particular attention is paid to the possible existence and determination of quenched c…
Hadron masses and decay constants in quenched QCD
M. Goeckeler, R. Horsley, D. Petters +4
We present results for the mass spectrum and decay constants using non-perturbatively O(a) improved Wilson fermions. Three values of and 30 different quark masses are used to o…
Light quark masses from the lattice
M. Gockeler, R. Horsley, B. Klaus +7
A completely non-perturbative estimate is given for the u/d and strange quark masses in quenched QCD using O(a) improved fermions and, for comparison, Wilson fermions. For improved…
A Lattice Determination of Light Quark Masses
M. Gockeler, R. Horsley, H. Oelrich +5
A fully non-perturbative lattice determination of the up/down and strange quark masses is given for quenched QCD using both, improved Wilson fermions and ordinary Wilson fer…
Nucleon form factors and O(a) Improvement
S. Capitani, M. Gockeler, R. Horsley +9
Nucleon form factors have been extensively studied both experimentally and theoretically for many years. We report here on new results of a high statistics quenched lattice QCD cal…
