Jets are the experimental signatures of quarks and gluons produced in high-energy processes such as head-on proton-proton collisions. As quarks and gluons have a net colour charge and cannot exist freely due to colour-confinement, they are not…

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. The ADD model (Arkani-Hamed, Dimopoulos, and Dvali) offers an…

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),…

The CMS experiment has submitted a paper for publication describing the first observation of a new, excited bottom (or beauty) baryon known as the Ξ*b0, with a…

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…
