Observation of a new boson with mass near 125 GeV in pp collisions at √s = 7 and 8 TeV
(2013-06-20)
A detailed description is reported of the analysis used by the CMS Collaboration in the search for the standard model Higgs boson in pp collisions at the LHC, which led to the observation of a new boson. The data sample ...
Measurement of the tt¯ production cross section in the all-jet final state in pp collisions at √s = 7 TeV
(2013-05-14)
A measurement is presented of the tt¯ production cross section (σtt¯) in proton-proton collisions at a centre-of-mass energy of 7 TeV, in the all-jet final state that contains at least six jets, two of which are tagged ...
Charged particle transverse momentum spectra in pp collisions at √s = 0:9 and 7 TeV
(2011-08-19)
The charged particle transverse momentum (pT) spectra are presented for pp collisions at √s = 0.9 and 7 TeV. The data samples were collected with the CMS detector at the LHC and correspond to integrated luminosities of ...
Measurement of the inclusive W and Z production cross sections in pp collisions at √s = 7 TeV with the CMS experiment
(2011-10-27)
A measurement of inclusive W and Z production cross sections in pp collisions at √s = 7 TeV is presented. The electron and muon decay channels are analyzed in a data sample collected with the CMS detector at the LHC and ...
Suppression of non-prompt J/ψ, prompt J/ψ, and Y(1S) in PbPb collisions at √s NN = 2.76 TeV
(2012-05-14)
Yields of prompt and non-prompt J/ψ, as well as Υ (1S) mesons, are measured by the CMS experiment via their μ+μ− decays in PbPb and pp collisions at √sNN = 2.76 TeV for quarkonium rapidity |y| < 2.4. Differential cross ...
Search for the standard model Higgs boson in the H → ZZ → ℓ+ℓ−τ+τ− decay channel in pp collisions at √s = 7 TeV
(2012-03-26)
A search is reported for the standard model Higgs boson in the H → ZZ → ℓ+ℓ−τ +τ − decay mode, where ℓ = μ or e, in proton-proton collisions at √s =7 TeV, corresponding to an integrated luminosity of 4.7 fb−1 collected ...
Search for dark matter and large extra dimensions in monojet events in pp collisions at √s = 7 TeV
(2012-09-21)
A search has been made for events containing an energetic jet and an imbalance
in transverse momentum using a data sample of pp collisions at a center-of-mass energy
of 7 TeV. This signature is common to both dark matter ...
Search for new physics with long-lived particles decaying to photons and missing energy in pp collisions at √s = 7 TeV
(2012-11-30)
A search is performed for long-lived neutral particles decaying into a photon and invisible particles. An example of such a signature is the decay of the lightest neutralino with nonzero lifetime into a gravitino and a ...
Search for stopped long-lived particles produced in pp collisions at √s = 7 TeV
(2012-08-03)
A search has been performed for long-lived particles that have stopped in the CMS detector, during 7 TeV proton-proton operations of the CERN LHC. The existence of such particles could be inferred from observation of their ...
Search for new physics with jets and missing transverse momentum in pp collisions at √s = 7 TeV
(2011-08-31)
A search for new physics is presented based on an event signature of at least
three jets accompanied by large missing transverse momentum, using a data sample corresponding
to an integrated luminosity of 36 pb−1
collected ...
