Abstract: (AIP)
We present results from the QCDSF/UKQCD collaboration for the electromagnetic form factors, axial charges and momentum fractions for the hyperons. The simulations are performed on our new ensembles generated with 2+1 flavours of dynamical O(a)‐improved Wilson fermions. A unique feature of these configurations is that the quark masses are tuned so that the singlet quark mass is held fixed at its physical value. We use 5 such choices of the individual quark masses on 24 3 ×48 lattices with a lattice spacing of about 0.078 fm.- 11.30.Rd
