Large Area Silicon Tracking: New Perspectives

The successful running of the large area Silicon trackers of ATLAS and CMS at LHC, and the ongoing R&D for the upgrade of these tracking systems, in various stages, over this decade, are a full proof of this technology and of its still impressive potential. The Linear Collider project is waiting for the possible discovery of a light Higgs at LHC maybe by end of 2012. These facts opened a new phase for the R&D on Silicon tracking for the Linear Collider, with enhanced synergy with LHC, Astrophysics and other HEP experiments, thus leading to new perspectives and alternatives.
