Determination of ${\Lambda }_{\overline{MS}}$ from quenched and $N_f=2$ dynamical QCD

S. Booth, M. Göckeler, R. Horsley +8

The scale parameter ${\Lambda }_{\overline{MS}}$ is computed on the lattice in the quenched approximation and for $N_f=2$ flavors of light dynamical quarks. The dynamical calculation is d…
