Measurement of the Z boson differential cross section in transverse momentum and rapidity in proton-proton collisions at 8 TeV
(2015-10-07)
We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy s=8 TeV, corresponding to an integrated luminosity ...
Measurement of prompt J/ψ pair production in pp collisions at √s = 7 Tev
(2014-09-17)
Production of prompt J/ψ meson pairs in proton-proton collisions at √s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb−1. The two J/ψ ...
Measurement of the underlying event activity using charged-particle jets in proton-proton collisions at √s = 2.76 TeV
(2015-09-21)
A measurement of the underlying event (UE) activity in proton-proton collisions
is performed using events with charged-particle jets produced in the central pseudorapidity
region (|η
jet| < 2) and with transverse momentum ...
Measurement of the cross section ratio σttbb/σttjj in pp collisions at √s=8 TeV
(2015-06-30)
The first measurement of the cross section ratio σttbb/σttjj is presented using a data sample corresponding
to an integrated luminosity of 19.6 fb−1 collected in pp collisions at √s = 8 TeV with the CMS detector at
the ...
Measurement of the tt¯ production cross section in the dilepton channel in pp collisions at √s = 8 TeV
(2014-02-05)
The top-antitop quark ( tt¯) production cross section is measured in proton-proton collisions at √s = 8 TeV with the CMS experiment at the LHC, using a data sample corresponding to an integrated luminosity of 5.3 fb−1. ...
J/ψ and ψ (2S) production in pp collisions at √s = 7 TeV
(2012-02-07)
A measurement of the J/ψ and ψ(2S) production cross sections in pp collisions at √s = 7TeV with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 pb−1. Using a fit ...
Constraints on the Higgs boson width from off-shell production and decay to Z-boson pairs
(2014-09-07)
Constraints are presented on the total width of the recently discovered Higgs boson, ΓH, using its relative
on-shell and off-shell production and decay rates to a pair of Z bosons, where one Z boson decays
to an electron ...
Search for resonant pair production of Higgs bosons decaying to two bottom quark-antiquark pairs in proton-proton collisions at 8 TeV
(2015-10-07)
A model-independent search for a narrow resonance produced in proton-proton collisions at √s=8 TeV and decaying to a pair of 125 GeV Higgs bosons that in turn each decays into a bottom quark-antiquark pair is performed by ...
Search for neutral MSSM Higgs bosons decaying into a pair of bottom quarks
(2015-11-11)
A search for neutral Higgs bosons decaying into a bb¯ quark pair and produced in association with at least one additional b quark is presented. This signature is sensitive to the Higgs sector of the minimal supersymmetric ...
Search for supersymmetry in pp collisions at √s = 8 TeV in events with a single lepton, large jet multiplicity, and multiple b jets
(2014-04-18)
Results are reported from a search for supersymmetry in pp collisions at a center-of-mass energy of
8 TeV, based on events with a single isolated lepton (electron or muon) and multiple jets, at least
two of which are ...
