Flavor tagging studies for a high performance vertex detector

Abstract

The ability to distinguish the flavor of jets formed in an event is a very important parameter to evaluate, when designing a high performance vertex detector to use in a future e+e− linear collider. In this work we concentrate on a CCD (Charged Coupled Device) pixel vertex detector. We first evaluate the basic tracking performance. We then estimate the flavor tagging performance of the present detector layout, using a neural network approach. We conclude by studying the energy dependence of the performance.
