 The CMS ECAL Upgrade for Precision Crystal Calorimetry at the HL-LHC / Petyt, David Anthony (Rutherford) /CMS Collaboration The electromagnetic calorimeter (ECAL) of the Compact Muon Solenoid Experiment (CMS) is operating at the Large Hadron Collider (LHC) in 2016 with proton-proton collisions at 13 TeV center-of-mass energy and at a bunch spacing of 25 ns. Challenging running conditions for CMS are expected after the High-Luminosity upgrade of the LHC (HL-LHC). [...] CMS-CR-2018-006.- Geneva : CERN, 2018 - 8 p.

 Systematic studies of charge-dependent azimuthal correlation in pPb and PbPb collisions at the LHC / Tu, Zhoudunming (Rice U.) /CMS Collaboration Studies of charge-dependent azimuthal correlations for same- and opposite-sign particle pairs are presented in PbPb collisions at 5.02 TeV and pPb collisions at 5.02 and 8.16 TeV, with the CMS experiment at the LHC. The azimuthal correlations are evaluated with respect to the second- and also higher-order event planes, as a function of particle pseudorapidity and transverse momentum, and event multiplicity.

 Operation and Performance of the CMS Outer Tracker / Butz, Erik Manuel (KIT, Karlsruhe, EKP) /CMS Collaboration The CMS Silicon Strip Tracker with its more than 15000 silicon modules and 200\,m$^2$ of active silicon area has been running together with the other subsystems of CMS for several years. We present the performance of the detector in the LHC Run 2 data taking. [...] CMS-CR-2017-428.- Geneva : CERN, 2017 - 11 p.

 Beam-dynamic effects at the CMS BRIL van der Meer scans / Babaev, Anton (TOMSK-POLYTEC) /CMS Collaboration The CMS Beam Radiation Instrumentation and Luminosity Project (BRIL) is responsible for the simulation and measurement of luminosity, beam conditions and radiation fields in the CMS experiment. The project is engaged in operating and developing new detectors (luminometers), adequate for the experimental conditions associated with high values of instantaneous luminosity delivered by the CERN LHC.

 Photon-photon measurements in CMS / Chudasama, Ruchi (Bhabha Atomic Res. Ctr.) /CMS Collaboration We discuss the measurement of photon-photon processes using data collected by the CMS experiment in pp collisions at $\sqrt{s}$ = 7 and 8 TeV and in PbPb collisions at $\sqrt{s_{_{{\rm NN}}}}= 5.02$ TeV..

 CMS Pixel detector development for the HL-LHC / Schwandt, Joern (Hamburg U.) /CMS Collaboration An upgrade program is underway which will bring the luminosity of the LHC up to about 7.5x10$^{34}$ cm$^{-2}$s$^{-1}$ in 2027, with the goal of an integrated luminosity of 3000~fb$^{-1}$ by the end of 2037. This High Luminosity scenario, HL-LHC, will present new challenges of higher data rates and increased radiation hardness for the pixel detector (a non-ionizing fluence of 2x10$^{16}$~n$_{eq}$/cm$^2$ and an ionizing dose of 10~MGy, is expected on the inner pixel layer for 3000~fb$^{-1}$ integrated luminosity).

 Alignment of the upgraded CMS pixel detector / Schroder, Matthias (KIT, Karlsruhe, EKP) /CMS Collaboration The all-silicon tracking system of the CMS experiment provides excellent resolution for charged tracks and an efficient tagging of heavy-flavour jets. After a new pixel detector has been installed during the LHC technical stop at the beginning of 2017, the positions, orientations, and surface curvatures of the sensors needed to be determined with a precision at the order of a few micrometres to ensure the required physics performance.

 The CMS Outer Tracker for HL-LHC / Dierlamm, Alexander Hermann (KIT, Karlsruhe, EKP) /CMS Collaboration The LHC is planning an upgrade program, which will bring the luminosity to about $5-7\times10^{34}$~cm$^{-2}$s$^{-1}$ in 2026, with a goal of an integrated luminosity of 3000 fb$^{-1}$ by the end of 2037. This High Luminosity LHC scenario, HL-LHC, will require a preparation program of the LHC detectors known as Phase-2 Upgrade. [...] CMS-CR-2018-014.- Geneva : CERN, 2018 - 7 p.
