Abstract

Building on the success of the current KEKB Flavour Factory and the Belle experiment, which helped to firmly establish the CKM picture of quark mixing and CP violation in the Standard Model, a luminosity upgrade of the asymmetric e +e − machine is planned. This new Super Flavour Factory, SuperKEKB, will deliver a luminosity of 8×10 35 cm −2 s −1, a factor 40 of increase over the present luminosity world record. It is foreseen to begin its operation in 2013. With these increased statistics, a new silicon vertex detector is needed in order to obtain precise decay vertex resolution measurements; these new precise measurements in the flavour sector can probe new physics well beyond the scales accessible to direct observations.
