I=2 pion scattering length with chirally improved fermions — •Dieter Hierl, Christof Gattringer, and Andreas Schäfer — University of Regensburg

We report on a lattice calculation of the pion scattering length in the I=2 channel using the chirally improved lattice Dirac operator. The scattering length is extracted by using the standard finite volume technique of Lüscher. We use different lattice sizes and discuss several extrapolations to the chiral limit. Finally we compare our results with the latest experimental data.
