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 ...
Inclusive search for a vector-like T quark with charge 2/3 in pp collisions at √s=8 TeV
(2014-02-05)
A search is performed for a massive new vector-like quark T, with charge 2
3 , that is pair produced together
with its antiparticle in proton–proton collisions. The data were collected by the CMS experiment at the
Large ...
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 W′→tb decays in the lepton + jets final state in pp collisions at √s = 8 TeV
(2014-05-23)
Results are presented from a search for the production of a heavy gauge boson W′ decaying into a top and a bottom quark, using a data set collected by the CMS experiment at √s = 8 TeV and corresponding to an integrated ...
Search for quark compositeness in dijet angular distributions from pp collisions at √s = 7 TeV
(2012-05-14)
A search for quark compositeness using dijet angular distributions from pp
collisions at √s = 7 TeV is presented. The search has been carried out using a data sample
corresponding to an integrated luminosity of 2.2 fb−1, ...
