On request of the FSQ PAG a run with very low pile-up (PU = 0.037) was taken for minimum bias and underlying event studies. Trigger information was exchanged between CMS and TOTEM and a common dataset has been obtained.

A measurement of the underlying event (UE) activity in proton-proton collisions at a centre-of-mass energy of 7 TeV is performed using Drell-Yan events in a data sample corresponding to an integrated luminosity of 2.2 fb−1 (inverse femtobarns),…

A search is presented for a massive particle, generically referred to as a Z′, decaying into a t-tbar pair. The search focuses on Z′ resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which yield collimated decay…

The production of b jets in association with a Z/γ* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV and recorded by the CMS detector. The inclusive production rates for Z/γ* + b-jet is…

Results are presented from a search for heavy bottom-like quarks, produced in pairs in pp collisions at √s = 7 TeV, undertaken with the CMS experiment at the LHC. The b′ quarks are assumed to decay exclusively to a top quark and a W boson (tW). The…

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…

Results are presented from a search for new physics in which the final state contains a photon (γ) and missing transverse energy (MET). The data correspond to an integrated luminosity of 5.0 fb−1 (inverse femtobarns) collected in pp collisions at √s…

The LHC provides CMS with millions of collisions each second, and a wealth of physics data is obtained from the proton-proton interactions. In order to record all these data for analyses, all CMS sub-detectors have to be performing optimally. If you…

This week the CMS collaboration will publish the results of its search for the Higgs boson that were presented at CERN in December 2011 [1].
Nine papers will be submitted for publication using the entire data sample of proton-proton collisions…
