Abstract: The Phase 2 upgrade of the LHC, presents a very interesting opportunity for the CMS to follow a more ambitious and diverge physics program than in Phase 1. The total integrated luminosity is planned to reach 3000 1/fb with an average of 200 p-p collisions per bunch crossing. In order to cope with the new harsh environment, the CMS detector will also be upgraded both in terms of hardware and software. One of the most significant detector upgrades will be in the tracker and it will enable the reconstruction of tracks at the Level 1 trigger stage. To take full advantage of this upgrade, a new track-finding triggering system based on FPGA will be introduced. The L1 track candidates will be reconstructed using a projective binning algorithm based on the Hough Transform, followed by a combinatorial Kalman Filter. This presentation will review the most important developments on the L1 track reconstruction algorithms and highlight the new possibilities for triggering (like displaced signatures, very rare decays etc).
