摘要：In this talk we report on recent results of the QCDSF/UKQCD Collaboration on investigations of baryon structure using configurations generated with Nf = 2+1 dynamical flavours of O(a)- improved Wilson fermions. With the strange quark mass as an additional dynamical degree of freedom in our simulations we avoid the need for a partially quenched approximation when investigating the properties of particles containing a strange quark, e.g. the hyperons. In particular, we will focus on the nucleon and hyperon axial coupling constants and quark momentum fractions.
