We present an initiatory study of quark helicity flip generalized parton
distributions (GPDs) in n_f=2 lattice QCD, based on clover-improved Wilson
fermions for a large number of coupling constants and pion masses. Quark
helicity flip GPDs yield essential information on the transverse spin structure
of the nucleon. In this work, we show first results on their lowest moments and
dipole masses and study the corresponding chiral and continuum extrapolations.Comment: 15 pages, 6 figure
