Assessment of Two Advanced Aluminium-Based Metal Matrix Composites for Application to High Energy Physics Detectors / Buchanan, Katie Elizabeth (CERN) ; Sgobba, Stefano (CERN) ; Celuch, Michal Dalemir (CERN) ; Perez Gomez, Francisco (CERN) ; Onnela, Antti (CERN) ; Rose, Pierre (CERN) ; Postema, Hans (CERN ; Cornell U.) ; Pentella, Mariano (CERN) ; Lacombe, Guillaume (Unlisted, FR) ; Thomas, Benjamin (Unlisted, FR) et al.
The Outer Tracker of the Compact Muon Solenoid (CMS), one of the large experiments at the CERN Large Hadron Collider, will consist of about 13,200 modules, each built up of two silicon sensors. The modules and support structures include thousands of parts that contribute to positioning and cooling the sensors during operation at −30 °C. [...]

Manufacturing technologies and joining methods of metallic thin-walled pipes for use in high pressure cooling systems / McNair, Sophie A M (Bath U.) ; Chaharsooghi, Alborz Shokrani (Bath U.) ; Carnevale, Mauro (Bath U.) ; Rhead, Andrew (Bath U.) ; Onnela, Antti (CERN) ; Daguin, Jerome (CERN) ; Cichy, Kamil (CERN) ; Postema, Hans (Cornell U.) ; Bacchetta, Nicola (CERN) ; French, Thomas (CERN) et al.
Small diameter thin-walled pipes, typically with a diameter less than 20 mm and a ratio of outer diameter to wall thickness is 20 or above, have increasingly become a key value adding factor for a number of industries including medical applications, electronics and chemical industries. In high-energy physics experiments, thin-walled pipes are needed in tracking detector cooling systems where the mass of all components needs to be minimised for physics measurement reasons. [...]

Strategies and performance of the CMS silicon tracker alignment during LHC Run 2 / CMS Collaboration
The strategies for and the performance of the CMS silicon tracking system alignment during the 2015-2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. [...]

Precision measurement of the structure of the CMS inner tracking system using nuclear interactions / CMS Collaboration
The structure of the CMS inner tracking system has been studied using nuclear interactions of hadrons striking its material. Data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are used to reconstruct millions of secondary vertices from these nuclear interactions. [...]

Physics motivations and expected performance of the CMS muon system upgrade with triple-GEM detectors / Venditti, Rosamaria (Bari U. ; INFN, Bari) ; Abbaneo, Duccio (CERN) ; Abbrescia, Marcello (Bari U. ; INFN, Bari) ; Aleksandrov, Andrey B (Lebedev Inst.) ; Benussi, Luigi (Frascati) ; Beni, Noemi (KLTE-ATOMKI) ; Bianco, Stefano (Frascati) ; Calabria, Cesare (Bergamo U. ; INFN, Pavia) ; Caponero, Michele (Frascati) ; Hernandez, Alfredo Martin Castaneda (CERN) et al. /CMS GEM
For the LHC High Luminosity phase (HL-LHC) the CMS GEM Collaboration is planning to in- stall new large size triple-GEM detectors in the forward region of the muon system (1.5< j h |<2.2) of the CMS detector. The muon reconstruction with triple-GEM chambers information included have been successfully integrated in the official CMS software, allowing physics studies to be carried out. [...]

Description and performance of track and primary-vertex reconstruction with the CMS tracker / CMS Collaboration
A description is provided of the software algorithms developed for the CMS tracker both for reconstructing charged-particle trajectories in proton-proton interactions and for using the resulting tracks to estimate the positions of the LHC luminous region and individual primary-interaction vertices. Despite the very hostile environment at the LHC, the performance obtained with these algorithms is found to be excellent. [...]

Alignment of the CMS tracker with LHC and cosmic ray data / CMS Collaboration
The central component of the CMS detector is the largest silicon tracker ever built. The precise alignment of this complex device is a formidable challenge, and only achievable with a significant extension of the technologies routinely used for tracking detectors in the past. [...]

A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider / CMS Collaboration
The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force—the W+, W–, and Z0 bosons—as well as to the fundamental quarks and leptons.

Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC / CMS Collaboration
Results are presented from searches for the standard model Higgs boson in proton-proton collisions at $\sqrt{s}$=7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at 8 TeV. The search is performed in five decay modes: $\gamma\gamma$, ZZ, WW, $\tau^+ \tau^-$, and $b\bar{b}$. [...]
