Volume independence of c_SW verified
Preliminary lattice spacing estimates provided
Abstract
We determine the parameter c_SW required for O(a)-improvement of the three flavor Wilson fermion action together with the tree-level Symanzik improved gauge action. The standard improvement condition is employed for a range of couplings. Additionally, we perform a check of the volume independence of c_SW and provide a preliminary estimate of the lattice spacing at our largest values of g_0^2.
