Abstract:In this talk we discuss at hand of two examples the crucial role played by self consistency in hadron physics. The first example concerns the quark-mass dependence of the baryon octet and decuplet masses. It is shown that within a self consistent one-loop approach based on the chiral Lagrangian the 'mysterious' quark-mass dependence of the Ξ mass predicted by the MILC collaboration may be recovered in terms of a discontinuous chiral extrapolation. This is a consequence of self consistency imposed on the partia… Show more
