Probing the chiral limit with clover fermions I: The meson sector
Presenter: Gerrit Schierholz — DESY
Steady improvements of the HMC algorithm made it possible to simulate QCD with Nf=2 flavors of nonperturbatively O(a) improved Wilson fermions at light quark masses. We present results for meson masses and decay constants, including a first identification of the rho meson as a resonance. We compare our results with the predictions of chiral perturbation theory in the finite and infinite volume to correct for finite size effects and to determine the pertinent low energy constants.
