Description

We report on a scaling test of several mesonic observables in the non-perturbatively O(a) improved Wilson theory with two flavors of dynamical quarks. The observables are constructed in a fixed volume of 2.4 fm x (1.8 fm)3 with Schroedinger functional boundary conditions. No significant scaling violations are found. Using the kaon mass determined, we update our estimate of the Lambda parameter to ΛMS-bar(2)/mK = 0.52(6).
