 Precision QCD Measurements from CMS / Cerci, Salim (Istanbul U.) /CMS Collaboration Recent measurements of jet events are presented which test QCD with unprecedented precision. The measurements are based on Run 2 data collected with the CMS detector at the LHC. [...] CMS-CR-2021-131.- Geneva : CERN, 2021 - 5 p.

 Status and Commissioning of the CMS Experiment / Buchmuller, Oliver (Imperial Coll., London) ; Schilling, Frank-Peter (KIT, Karlsruhe, EKP) After a brief overview of the Compact Muon Solenoid (CMS) experiment, the status of construction and installation is described in the first part of the note. The second part of the document is devoted to a discussion of the general commissioning strategy of the CMS experiment, with a particular emphasis on trigger, calibration and alignment. [...] CMS-CR-2007-001.- Geneva : CERN, 2006 - 10 p. Fulltext: PDF; In : 11th International Conference on B-physics at Hadron Machines, Oxford, UK, 25 - 29 Sep 2006

 The upgrade of the CMS pixel detector / Favaro, Carlotta (IRFU, Saclay) /CMS Collaboration The CMS inner pixel detector system is planned to be upgraded during the first phase of LHC upgrades. The plans call for an ultra low mass system with four barrel layers with three disks on either end. [...] CMS-CR-2010-286.- Geneva : CERN, 2010 - 6 p.

 Xrootd Monitoring for the CMS experiment / Tadel, Matevz (UC, San Diego) /CMS Collaboration During spring and summer 2011 CMS deployed Xrootd front-end servers on all US T1 and T2 sites. This allows for remote access to all experiment data and is used for user-analysis, visualization, running of jobs at T2s and T3s when data is not available at local sites, and as a fail-over mechanism for data-access in CMSSW jobs. Monitoring of Xrootd infrastructure is implemented on three levels. [...] CMS-CR-2012-086.- Geneva : CERN, 2012 - 10 p.

 Stitched Together Transitioning CMS to a Hierarchical Threaded Framework / Jones, Christopher Duncan (Fermilab) ; Sexton-Kennedy, Elizabeth (Fermilab) /CMS Collaboration Modern computing hardware is transitioning from using a single high frequency complicated computing core to many lower frequency simpler cores. As part of that transition, hardware manufacturers are urging developers to exploit concurrency in their programs via operating system threads. [...] CMS-CR-2013-393.- Geneva : CERN, 2013 - p.

 Prospects for BSM searches at the high-luminosity LHC with the CMS detector / Shchutska, Lesya (Zurich, ETH) /CMS Collaboration After a series of upgrades the Large Hadron Collider will deliver an integrated luminosity of up to 3000/fb with $\sqrt s$ = 14 GeV for each experiment. Aspects of the supersymmetry and other beyond the standard model (BSM)search programme are discussed for this scenario. [...] CMS-CR-2014-347.- Geneva : CERN, 2014 - 7 p.

 Rate-capability study of a four-gap phenolic RPC with a $^{137}$Cs source / Lee, Kyong Sei (Korea U.) /CMS Collaboration In this paper, we report on the systematic rate-capability study of four-gap phenolic resistive plate chambers (RPCs), with cosmic muons and gamma rays emitted from a $^{137}$Cs source. A prototype four-gap RPC with a gap thickness of 1.06 mm has been constructed with 2-mm thick phenolic high-pressure-laminated (HPL) plates. [...] CMS-CR-2014-032.- Geneva : CERN, 2014 - 9 p.

 CMS recent results in Heavy Flavour production and properties / Pompili, Alexis (INFN, Bari ; Bari U.) /CMS Collaboration Recent CMS results in the field of Heavy Flavour production and properties are reviewed. The measurement of differential prompt production cross sections of S-wave quarkonia in pp collisions at the center-of-mass energy $\sqrt{s}=13$TeV is reported since these are important for the study of the heavy-quark production mechanisms in quantum chromodynamics (QCD).

 The new Fast Beam Condition Monitor using diamond and silicon sensors for luminosity measurement at CMS / Guthoff, Moritz (DESY) /CMS Collaboration The Fast Beam Condition Monitor (BCM1F) is used in CMS to measure beam induced background and precision luminosity. The system in its current implementation was first installed in 2014, equipped with single-crystalline (sCVD) diamond sensors. [...] CMS-CR-2018-104.- Geneva : CERN, 2018 - 3 p.

 Recent precision W/Z measurements at the LHC (all relevant DY measurements), including full Run 2 and HL-LHC prospects / Cipriani, Marco (CERN) /ALICE,ATLAS,CMS and LHCB Collaborations Precision measurements of W and Z boson cross sections and other properties are a powerful tool to validate theoretical calculations of the standard model, and are also essential in searches for new physics phenomena. These bosons are copiously produced in proton-proton collisions at the LHC, which permits several measurements to be performed differentially in many kinematic variables, often with negligible statistical uncertainties.
