摘要：

As a test of quenched lattice twisted mass QCD, we compute the non-perturbatively O(a) improved pseudoscalar and vector meson masses and the pseudoscalar decay constant down to M-PS/M-V = 0.407(13) at beta = 6 in large volume. We check the absence of exceptional configurations and - by further data at beta = 6.2 - the size of scaling violations. The CPU time cost for reaching a given accuracy is close to that with ordinary Wilson quarks at M-PS/M-V similar or equal to 0.6 and grows smoothly as M-PS/M-V decreases.
