Abstract

The SuperB asymmetric e⁺ e^- collider has been designed to deliver a luminosity greater than 10³⁶ cm^-2 s^-1 maintaining moderate beam currents. Comparing to current B-Factories, the reduced center-of-mass boost of the SuperB machine requires an improved vertex resolution to allow precision measurements sensitive to New Physics. Therefore the SuperB Silicon Vertex Tracker will be equipped with an innermost Layer0 with a radius of about 1.5 cm, high granularity, low material budget and able to withstand a background rate of several MHz/cm². We report on the status of the R&D on the different options under study for the Layer0: DNW MAPS, hybrid pixels and thin pixels developed with vertical integration technology.
