Petal Integration for the CMS Tracker End Caps / Bergauer, Thomas ; Dragicevic, Marko ; Friedl, Markus ; Hansel, S ; Hrubec, Josef ; Krammer, Manfred ; Pernicka, Manfred ; Beaumont, Willem ; De Wolf, Eddi A ; Bouhali, Othmane et al.
This note describes the assembly and testing of the 292 petals built for the CMS Tracker End Caps from the beginning of 2005 until the summer of 2006. Due to the large number of petals to be assembled and the need to reach a throughput of 10 to 15 petals per week, a distributed integration approach was chosen. [...]

Integration of the End Cap TEC+ of the CMS Silicon Strip Tracker / Tracker End Cap Collaboration
The silicon strip tracker of the CMS experiment has been completed and inserted into the CMS detector in late 2007. The largest sub-system of the tracker is its end cap system, comprising two large end caps (TEC) each containing 3200 silicon strip modules. [...]

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. [...]

Track Reconstruction with Cosmic Ray Data at the Tracker Integration Facility / CMS Collaboration
The subsystems of the CMS silicon strip tracker were integrated and commissioned at the Tracker Integration Facility (TIF) in the period from November 2006 to July 2007. As part of the commissioning, large samples of cosmic ray data were recorded under various running conditions in the absence of a magnetic field. [...]

The CMS Barrel Calorimeter Response to Particle Beams from 2 to 350 GeV/c / CMS HCAL/ECAL Collaboration
The response of the CMS barrel calorimeter (electromagnetic plus hadronic) to hadrons, electrons and muons over a wide momentum range from 2 to 350 GeV/c has been measured. To our knowledge, this is the widest range of momenta in which any calorimeter system has been studied. [...]

Technical Design Report for the Phase-I Upgrade of the ATLAS TDAQ System / ATLAS Collaboration
The Phase-I upgrade of the ATLAS Trigger and Data Acquisition (TDAQ) system is to allow the ATLAS experiment to efficiently trigger and record data at instantaneous luminosities that are up to three times that of the original LHC design while maintaining trigger thresholds close to those used in the initial run of the LHC..

A Particle Consistent with the Higgs Boson Observed with the ATLAS Detector at the Large Hadron Collider / ATLAS Collaboration
Nearly 50 years ago, theoretical physicists proposed that a field permeates the universe and gives energy to the vacuum. This field was required to explain why some, but not all, fundamental particles have mass. [...]

Design, Performance, and Calibration of CMS Hadron Endcap Calorimeters / CMS HCAL Collaboration
Detailed measurements have been made with the CMS hadron calorimeter endcaps (HE) in response to beams of muons, electrons, and pions. Readout of HE with custom electronics and hybrid photodiodes (HPDs) shows no change of performance compared to readout with commercial electronics and photomultipliers. [...]

Synchronization and Timing in CMS HCAL / Baiatian, G (Yerevan Phys. Inst., Yerevan, Armenia) ; Sirunyan, Albert M ; Emeliantchik, Igor ; Massolov, V ; Shumeiko, Nikolai ; Stefanovich, R ; Damgov, Jordan ; Dimitrov, Lubomir ; Genchev, Vladimir ; Piperov, Stefan et al. /CMS Hadron Calorimeter Readout Group
The synchronization and timing of the hadron calorimeter (HCAL) for the Compact Muon Solenoid has been extensively studied with test beams at CERN during the period 2003-4, including runs with 40 MHz structured beam. The relative phases of the signals from different calorimeter segments are timed to 1 ns accuracy using a laser and equalized using programmable delay settings in the front-end electronics. [...]
