Evaluation of a multi variated analysis for the selection of t-tbar multijet events in the current CMS implemented environment at LHC / Bacchi, William
In the present study we are using multi variate analysis techniques to discriminate signal from background in the fully hadronic decay channel of ttbar events [...]

CMS expects to manage many tens of peta bytes of data to be distributed over several computing centers around the world. The CMS distributed computing and analysis model is designed to serve, process and archive the large number of events that will be generated when the CMS detector starts taking data. [...]

Commissioning and performance of the CMS pixel tracker with cosmic ray muons / CMS Collaboration
The pixel detector of the Compact Muon Solenoid experiment consists of three barrel layers and two disks for each endcap. The detector was installed in summer 2008, commissioned with charge injections, and operated in the 3.8 T magnetic field during cosmic ray data taking. [...]

Measurement of the muon stopping power in lead tungstate / CMS Collaboration
A large sample of cosmic ray events collected by the CMS detector is exploited to measure the specific energy loss of muons in the lead tungstate (PbWO$_4$) of the electromagnetic calorimeter. The measurement spans a momentum range from 5 GeV/$c$ to 1 TeV/$c$. [...]

Performance of the CMS Level-1 trigger during commissioning with cosmic ray muons and LHC beams / CMS Collaboration
The CMS Level-1 trigger was used to select cosmic ray muons and LHC beam events during data-taking runs in 2008, and to estimate the level of detector noise. This paper describes the trigger components used, the algorithms that were executed, and the trigger synchronisation. [...]

Performance of CMS muon reconstruction in cosmic-ray events / CMS Collaboration
The performance of muon reconstruction in CMS is evaluated using a large data sample of cosmic-ray muons recorded in 2008. Efficiencies of various high-level trigger, identification, and reconstruction algorithms have been measured for a broad range of muon momenta, and were found to be in good agreement with expectations from Monte Carlo simulation. [...]

Commissioning and performance of the CMS silicon strip tracker with cosmic ray muons / CMS Collaboration
During autumn 2008, the Silicon Strip Tracker was operated with the full CMS experiment in a comprehensive test, in the presence of the 3.8 T magnetic field produced by the CMS superconducting solenoid. Cosmic ray muons were detected in the muon chambers and used to trigger the readout of all CMS sub-detectors. [...]

Performance of the CMS cathode strip chambers with cosmic rays / CMS Collaboration
The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. [...]

Performance of the CMS hadron calorimeter with cosmic ray muons and LHC beam data / CMS Collaboration
The CMS Hadron Calorimeter in the barrel, endcap and forward regions is fully commissioned. Cosmic ray data were taken with and without magnetic field at the surface hall and after installation in the experimental hall, hundred meters underground. [...]

CMS data processing workflows during an extended cosmic ray run / CMS Collaboration
The CMS Collaboration conducted a month-long data taking exercise, the Cosmic Run At Four Tesla, during October-November 2008, with the goal of commissioning the experiment for extended operation. With all installed detector systems participating, CMS recorded 270 million cosmic ray events with the solenoid at a magnetic field strength of 3.8 T. [...]
