Vertexing at the ILC

Abstract

The International Linear Collider (ILC )has been very prominently mentioned in the international strategy documents for high energy physics and here is a strong interest in Japan to become the host country for the ILC. Two detectors have been proposed for the ILC, the SiD and ILD concepts. They have both been validated by an international advisory committee and Detailed Baseline Designs have been presented in 2012. While both detectors are built for particle flow, their approach to tracking is quite distinct. While ILD uses a combination of a TPC with silicon detectors, SiD has an all-silicon detector approach to tracking, with a fully integrated tracker. First an overview of both concepts will be given and then the recent technology developments for both vertex and tracker sensors, as well as the state of the reconstruction software suites, will be reviewed.
