Abstract
We present results from the QCDSF/UKQCD collaboration for the transverse spin densities of octet baryons obtained from simulations using Nf = 2+1 flavours of O(a)-improved Wilson fermions. These densities are revealed through an analysis of the electromagnetic and tensor form factors of the octet baryons at two different lattice spacings with pion masses as low as 220 MeV. We find SU(3) flavour-breaking effects of the form factors and use these to extrapolate to the physical mass. Constructing combinations of Fourier transformed form factors reveal non-trivial spin densities in the transverse plane, with similar deformations across the baryon octet.
