      abstract     = {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.},
