Quark mass dependence of hadron masses from lattice QCD
UKQCD Collaboration, M. Foster, C. Michael
We discuss lattice methods to obtain the derivatives of a lattice meson mass with respect to the bare sea and valence quark masses. Applications are made to quenched and dynamical…
Cooling and the SU(2) Instanton Vaccuum
C. Michael, P. S. Spencer
We present results of an investigation into the nature of instantons in 4-dimensional pure gauge lattice \ obtained from configurations which have been cooled using an under…
Instanton size distributions from calibrated cooling
C. Michael, P. S. Spencer
Using an under-relaxed cooling algorithm we investigated the vacuum in the model and pure gauge . We calibrated the amount of cooling performed to have simil…
Lattice study of sphaleron transitions in a 2D O(3) sigma model
J. Kripfganz, C. Michael
A lattice approach is developed to measure the sphaleron free energy. Its feasibility is demonstrated through a Monte Carlo study of the two-dimensional O(3) sigma model.
