 Estimation of the material budget of the CMS Tracker using the triplet method / Roy Chowdhury, Suvankar (INFN, Pisa ; Pisa, Scuola Normale Superiore) /CMS Collaboration Silicon trackers are used extensively in high energy physics experiments. Estimation of the material budget of the tracker is crucial for the physics program of any experiment, especially for precision measurements, as it has a direct impact on reconstruction performance and calculation of systematic errors.

 Performance of 2S Modules of CMS Phase-2 Tracker in a Test Beam environment / Saha, Gourab (Saha Inst.) /CMS Collaboration The present CMS Tracker will be replaced by a new improved tracking detector for operation at the High Luminosity LHC\,(HL-LHC). The outer part of the new tracking detector will comprise modules with two closely spaced parallel silicon sensors with front-end ASICs capable of transmitting information about high transverse momentum tracks to the CMS Level-1 trigger system at the 40 MHz beam bunch crossing rate.

 The upgrade of the CMS Tracker at HL-LHC / La Rosa, Alessandro (CERN) /CMS Collaboration In the high luminosity scenario of the LHC (HL-LHC), which will bring the instantaneous luminosity up to 7.5\,$\times$\,$10^{34}$\,cm$^{-2}$s$^{-1}$, ATLAS and CMS will need to operate at up to 200 interactions per 25\,ns beam crossing and reaching up to 4000\,fb$^{-1}$ of integrated luminosity. To achieve their physics goals the experiments will need to improve the tracking and vertexing capability and the ability to selectively trigger on specific physics events at reasonable thresholds.

 Study of Interpad-gap of FBK (UFSD3) and HPK 3.1 Type sensors with Transient Current Technique / Bharthuar, Shudhashil (Helsinki Inst. of Phys.) /CMS Collaboration The Phase-2 upgrade of the Large Hadron Collider (LHC) to High-Luminosity LHC (HL-LHC) allows an increase in the operational luminosity value by a factor of 5--7 that will result in delivering 3000~fb$^{-1}$ or more integrated luminosity. Due to high luminosity, the number of interactions per bunch crossings (pileup) will increase up to a value of 140--200. [...] CMS-CR-2020-051.- Geneva : CERN, 2020 - 21 p.

 Tracker alignment of the CMS detector / Connor, Patrick (Hamburg U.) /CMS Collaboration The positions of the nearly twenty-thousand silicon sensors of the CMS central tracking system must be determined with a precision better than their intrinsic resolution in order to provide an optimal reconstruction of charged particle trajectories. The procedure, referred to as the alignment, includes also the adjustment of the orientations and the determination of the deviation from flatness of the sensor surfaces. Data-driven methods used to carefully align the detector and validate the alignment will be presented with CMS Run 2 data, collected from 2016 to 2018.

 The CMS tracker upgrade for the \\ High Luminosity LHC / Klein, Katja (Aachen, Tech. Hochsch.) The CMS detector features the world's largest silicon tracker, comprising a strip and a pixel detector. However, the CMS tracker is expected to reach the end of its lifetime after Run 3 of the LHC, and a new device will be installed during Long Shutdown 3.
