Machining jets
New algorithms from the Compact Muon Solenoid experiment use the ideas used in mobile phone facial recognition to better understand the collisions at the Large Hadron Collider.

Jets at CMS and the determination of their energy scale
Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions.

The search for microscopic black holes, as of March 2012
The search for microscopic black holes at the LHC is motivated by the hierarchy problem — the huge observed difference between the strengths of the electroweak and gravitational forces.

Ratios of dijet production cross sections as a function of the absolute difference in rapidity between jets in proton-proton collisions at sqrt(s) = 7 TeV
A study of dijet production in proton-proton collisions was performed at √s = 7 TeV for jets with pT > 35 GeV and |y| < 4.7[1] using data collected with the CMS detector at the LHC in 2010. Events with at least one pair of jets are denoted as “inclusive”, while events with exactly one…

Measurement of the t-channel single Top-quark production rates in pp collisions at 7 TeV
The Top quark is the heaviest of the six quarks of the Standard Model and was discovered only 16 years ago by the Tevatron experiments at Fermilab.

Search for Supersymmetry at the LHC in Events with Jets and Missing Transverse Energy
Read the paper: SUS-11-003 The analysis shows no excess of events over the Standard Model expectations.

Measurement of the tt-bar Production Cross Section in pp Collisions at 7 TeV in Lepton + Jets Events Using b-quark Jet Identification
Read the paper: TOP-11-003 The measured production rates of Top-antiTop pairs, where one lepton and four jets of particles is observed in the final state, show good agreement with Quantum Chromodynamics (QCD), the theory of the strong interaction.

Important heavy-ion results from CMS
The CMS experiment has made several unique measurements using data from LHC collisions of lead nuclei (PbPb, November 2010) at centre-of-mass energies of 2.76 TeV per nucleon pair.

Search for Supersymmetry in pp Collisions at 7 TeV with Jets and Missing Et
The Compact Muon Solenoid (CMS) Collaboration at CERN’s Large Hadron Collider (LHC) has announced the results of the search for supersymmetry (SUSY) in events with jets and missing transverse energy.

Search for microscopic black hole signatures at the Large Hadron Collider
The CMS experiment at CERN’s Large Hadron Collider (LHC) has completed a search for microscopic black holes produced in high-energy proton-proton collisions.
