Hadron spectrum from lattice QCD with light quark masses — •Carsten Urbach — Humboldt-Universitaet zu Berlin
We present recent results for the hadron spectrum obtained from lattice QCD simulations by the European Twisted Mass collaboration (ETMC). ETMC employs the so called twisted mass formulation of lattice QCD, which allows for large scale simulations with nf=2 or nf=2+1+1 flavours of light quarks.
We shall present results for meson masses and decay constants as well as for masses of the baryon octet and decuplet. We shall also discuss the extrapolation of these quantities to the chiral, continuum and thermodynamic limit.
