Abstract: | We calculate the disconnected contribution to the form factor for the semileptonic decay of a D-meson into a final state, containing a flavor singlet et meson. We use QCDSF nf=2+1 configurations at the flavor symmetric point mu=md=ms and the partially quenched approximation for the relativism charm quark. Several acceleration and noise reduction techniques for the stochastic estimation of the disconnected loop are tested. |
