Description
The present CMS pixel detector designed for a luminosity of 10^34 cm-2s-1 will have to be replaced at the end of 2016. The new upgraded detector will have higher tracking efficiency and lower mass with four barrel layers and three forward/backward disks to provide a hit coverage up to absolute pseudo-rapidities of 2.5. In a second stage, in order to maintain its physics reach during the high luminosity phase of the LHC (HL-LHC), when the machine is expected to deliver an instantaneous luminosity of 5 x 10^34 cm^-2 s^-1 for total of 3000 fb^-1, CMS will build a new tracker, comprising completely new pixel detector and outer tracker. The ongoing R&D activities on both pixel and strip sensors will be presented. The present status of the Inner and Outer Tracker projects will be illustrated, and the possible perspectives will be discussed.
