| 500 | _ | _ | |a The numerical configuration generation was performed using the BQCD lattice QCD program, [31], on the IBM BlueGeneL at EPCC (Edinburgh, United Kingdom), the BlueGeneL and P at NIC (Julich, Germany), the SGI ICE 8200 at HLRN (Berlin-Hannover, Germany) and the JSCC (Moscow, Russia). We thank all institutions. The BlueGene codes were optimized using Bagel [32]. The Chroma software library [33] was used in the data analysis. This work has been supported in part by the EU Grants No. 227431 (Hadron Physics2), No. 238353 (ITN STRONGnet) and by the DFG under contract SFB/TR 55 (Hadron Physics from Lattice QCD). J. M.

| 520 | _ | _ | |a QCD lattice simulations determine hadron masses as functions of the quark masses. From the gradients of these masses and using the Feynman-Hellmann theorem the hadron sigma terms can then be determined. We use here a novel approach of keeping the singlet quark mass constant in our simulations which upon using an SU(3) flavor symmetry breaking expansion gives highly constrained (i.e. few parameter) fits for hadron masses in a multiplet. This is a highly advantageous procedure for determining the hadron mass gradient as it avoids the use of delicate chiral perturbation theory. We illustrate the procedure here by estimating the light and strange sigma terms for the baryon octet. |
