Description
The talk reviews the geometric basis of the “PT” and “CW” approaches for the selection of high transverse momentum particles coming from primary interactions at sLHC. Starting from the definition of a small segment measurement (stub) of a particle trajectory it gives basic general constraints which contour the architecture of both methods. The sensor position with respect to the production vertex as well as the sensor structure and design are key factors the behavior of which is described by a-dimensional parameters according simple scaling laws. Using these tools the selection efficiency of high transverse momentum is discussed in a thorough way, with emphasis to the effects due to the Lorentz drift, non primary background particles, sensor dimension and position. The discussed predictions, while waiting the LHC collisions validation, can be verified with the cosmic rays data in the CMS Tracker.
