An estimate of the image decay form factor Original Research Article

We present the results of a lattice QCD calculation of the form factor relevant to image decay. Our final value, image, is obtained in the quenched approximation, and by extrapolating image image from the directly accessed H-heavy mesons to the meson B. We also show that the extrapolation from image (image) to image (image), leads to a result consistent with the one quoted above. On the other hand, our results are not accurate enough to solve the image flavor breaking effects in the form factor and we quote image, as our best estimate.
