Measurement of energy flow at large pseudorapidities in pp collisions at √s = 0.9 and 7 TeV
(Springer-Verlag, 2011-11)
The energy flow, dE/dη, is studied at large pseudorapidities in proton-proton collisions at the LHC, for centre-of-mass energies of 0.9 and 7 TeV. The measurements are made using the CMS detector in the pseudorapidity range ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier, 2012-12)
The results of a search for flavor changing neutral currents in top quark decays t→Zq in events with a topology compatible with the decay chain tt¯→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
Measurement of the inclusive production cross sections for forward jets and for dijet events with one forward and one central jet in pp collisions at √s = 7 TeV
(Springer-Verlag, 2012-06)
The inclusive production cross sections for forward jets, as well for jets in dijet events with at least one jet emitted at central and the other at forward pseudorapidities, are measured in the range of transverse momenta ...
Search for the standard model Higgs boson produced in association with a W or a Z boson and decaying to bottom quarks
(American Physical Society, 2014-01)
A search for the standard model Higgs boson (H) decaying to b[¯ over b] when produced in association with a weak vector boson (V) is reported for the following channels: W(μν)H, W(eν)H, W(τν)H, Z(μμ)H, Z(ee)H, and Z(νν)H. ...
Searches for Electroweak Neutralino and Chargino Production in Channels with Higgs, Z, and W Bosons in pp Collisions at 8 TeV
(American Physical Society, 2014-11)
Searches for supersymmetry (SUSY) are presented based on the electroweak pair production of neutralinos and charginos, leading to decay channels with Higgs, Z, and W bosons and undetected lightest SUSY particles (LSPs). ...
Measurement of Prompt ψ(2S) to J/ψ Yield Ratios in Pb-Pb and p-p Collisions at √s[subscript NN] = 2.76 TeV
(American Physical Society, 2014-12)
The ratio between the prompt ψ(2S) and J/ψ yields, reconstructed via their decays into μ[superscript +]μ[superscript -], is measured in Pb-Pb and p-p collisions at √s[subscript NN] = 2.76 TeV. The analysis is based on ...
Evidence for the 125 GeV Higgs boson decaying to a pair of τ leptons
(Springer-Verlag, 2014-05)
A search for a standard model Higgs boson decaying into a pair of τ leptons is performed using events recorded by the CMS experiment at the LHC in 2011 and 2012. The dataset corresponds to an integrated luminosity of 4.9 ...
Measurement of the ratio of the production cross sections times branching fractions of B [superscript ±][subscript c] → [J over ψπ [superscript ±]] and B[superscript ±] → [J over ψK [superscript ±]] and ℬ(B [superscript ±][subscript c] → [J over Ψ π [superscript ±] π [superscript ±] π [superscript ∓] [over ℬ(B [superscript ±][subscript c] → J [over Ψ π [superscript ±]]) in pp collisions at √s = 7 TeV

The ratio of the production cross sections times branching fractions (σ(B[superscript ± [subscript c])B(B[superscript ±] [subscript c]→J[over ψπ [superscript ±]])) [over (σ(B [superscript ±])B(B[superscript ±]→J/ψK[superscript ...
Search for heavy neutrinos and W bosons with right-handed couplings in proton–proton collisions at √s = 8 TeV
(Springer-Verlag, 2014-11)
A search for heavy, right-handed neutrinos, Nℓ ( ℓ=e,μ ), and right-handed W[subscript R] bosons, which arise in the left-right symmetric extensions of the standard model, has been performed by the CMS experiment. The ...
Observation of long-range, near-side angular correlations in pPb collisions at the LHC
(Elsevier, 2012-11)
Results on two-particle angular correlations for charged particles emitted in pPb collisions at a nucleon–nucleon center-of-mass energy of 5.02 TeV are presented. The analysis uses two million collisions collected with the ...
