摘要：We present results from the QCDSF/UKQCD collaboration for the electromagnetic and semileptonic form factors 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 243 ×48 lattices with a lattice spacing of about 0.078 fm.
