Abstract

We present preliminary results from the QCDSF/UKQCD collaborations for the second moment of the pion's distribution amplitude with two flavours of dynamical fermions. We use nonperturbatively determined renormalisation coefficients to convert our results to the scheme at . Employing a linear chiral extrapolation from our large pion masses , we find 〈ξ2〉=0.281(28), leading to a value of a2=0.236(82) for the second Gegenbauer moment.
