We present results of lattice QCD simulations with mass-degenerate up and down and mass-split strange and charm (N f = 2 + 1 + 1) dynamical quarks using Wilson twisted mass fermions at maximal twist. The tuning of the strange and charm quark masses is performed at two values of the lattice spacing a ∼∼ 0.078 fm and a ∼∼ 0.086 fm with lattice sizes ranging from L ∼∼ 1.9 fm to L ∼ ∼2.8 fm. We measure with high statistical precision the light pseudoscalar mass mPS and decay constant fps in a range 270 ∼< mPS ∼< 510 MeV and determine the low energy parameters f 0 and l̄ 3, 4 of SU(2) chiral perturbation theory. We use the two values of the lattice spacing, several lattice sizes as well as different values of the light, strange and charm quark masses to explore the systematic effects. A first study of discretisation effects in light-quark observables and a comparison to Nf = 2 results are performed. | |
