Search for Quark Compositeness with the Dijet Centrality Ratio in pp Collisions at $\sqrt{s}$ = 7 TeV / CMS Collaboration
A search for quark compositeness in the form of quark contact interactions, based on hadronic jet pairs (dijets) produced in proton-proton collisions at sqrt(s)=7 TeV, is described. The data sample of the study corresponds to an integrated luminosity of 2.9 inverse picobarns collected with the CMS detector at the LHC [...]

Search for Dijet Resonances in 7 TeV pp Collisions at CMS / CMS Collaboration
A search for narrow resonances in the dijet mass spectrum is performed using data corresponding to an integrated luminosity of 2.9 inverse pb collected by the CMS experiment at the LHC. Upper limits at the 95% confidence level (CL) are presented on the product of the resonance cross section, branching fraction into dijets, and acceptance, separately for decays into quark-quark, quark-gluon, or gluon-gluon pairs.

Observation of Long-Range, Near-Side Angular Correlations in Proton-Proton Collisions at the LHC / CMS Collaboration
Results on two-particle angular correlations for charged particles emitted in proton-proton collisions at center-of-mass energies of 0.9, 2.36, and 7 TeV are presented, using data collected with the CMS detector over a broad range of pseudorapidity (eta) and azimuthal angle ($\phi$). Short-range correlations in $\Delta\eta$, which are studied in minimum bias events, are characterized using a simple "independent cluster" parametrization in order to quantify their strength (cluster size) and their extent in $\eta$ (cluster decay width). [...]

CMS Tracking Performance Results from Early LHC Operation / CMS Collaboration
The first LHC pp collisions at centre-of-mass energies of 0.9 and 2.36 TeV were recorded by the CMS detector in December 2009. The trajectories of charged particles produced in the collisions were reconstructed using the all-silicon Tracker and their momenta were measured in the 3.8 T axial magnetic field. [...]

First Measurement of the Underlying Event Activity at the LHC with $\sqrt{s}$ = 0.9 TeV / CMS Collaboration
A measurement of the underlying activity in scattering processes with pT scale in the GeV region is performed in proton-proton collisions at $\sqrt{s}$ = 0.9 TeV, using data collected by the CMS experiment at the LHC. Charged hadron production is studied with reference to the direction of a leading object, either a charged particle or a set of charged particles forming a jet. [...]

Measurement of the charge ratio of atmospheric muons with the CMS detector / CMS Collaboration
We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental cavern at the CERN LHC. Muons were detected in the momentum range from 5 GeV/c to 1 TeV/c. [...]

Transverse-momentum and pseudorapidity distributions of charged hadrons in $pp$ collisions at $\sqrt{s}$ = 7 TeV / CMS Collaboration
Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at $\sqrt{s} = 7$~TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit-pairs, and fully reconstructed charged-particle tracks. [...]

First Measurement of Bose-Einstein Correlations in proton-proton Collisions at $\sqrt{s}$ =0.9 and 2.36 TeV at the LHC / CMS Collaboration
Bose-Einstein correlations have been measured using samples of proton-proton collisions at 0.9 and 2.36 TeV center-of-mass energies, recorded by the CMS experiment at the CERN Large Hadron Collider. The signal is observed in the form of an enhancement of pairs of same-sign charged particles with small relative four-momentum. [...]

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. [...]
