Study of the underlying event at forward rapidity in pp collisions at √s=0.9,2.76, and 7 TeV
(Springer Science and Business Media LLC, 2013)
© 2013, CERN. The underlying event activity in proton-proton collisions at forward pseudo-rapidity (—6.6 < η < —5.2) is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy ...
Search for flavor changing neutral currents in top quark decays in pp collisions at 7 TeV
(Elsevier BV, 2013)
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 tt̄→Wb+Zq→ℓνb+ℓℓq are presented. The search is performed with a data sample ...
Performance of τ-lepton reconstruction and identification in CMS
(IOP Publishing, 2012-01-01)
The performance of τ-lepton reconstruction and identification algorithms is studied using a data sample of proton-proton collisions at s = 7 TeV, corresponding to an integrated luminosity of 36 pb-1 collected with the CMS ...
Search for supersymmetry in proton-proton collisions at 13 TeV using identified top quarks
(American Physical Society, 2018-01)
A search for supersymmetry is presented based on proton-proton collision events containing identified hadronically decaying top quarks, no leptons, and an imbalance p [superscript miss] [subscript T] in transverse momentum. ...
Search for the Higgs Boson Decaying to Two Muons in Proton-Proton Collisions at √s = 13 TeV
(American Physical Society, 2019-01)
A search for the Higgs boson decaying to two oppositely charged muons is presented using data recorded by the CMS experiment at the CERN LHC in 2016 at a center-of-mass energy √s = 13 TeV, corresponding to an integrated ...
Comparing transverse momentum balance of b jet pairs in pp and PbPb collisions at sNN=5.02$$ \sqrt{s_{\mathrm{NN}}}=5.02 $$ TeV
(Springer, 2018-03)
The transverse momentum balance of pairs of back-to-back b quark jets in PbPb and pp collisions recorded with the CMS detector at the LHC is reported. The center-of-mass energy in both collision systems is 5.02 TeV per ...
Measurement of the charge ratio of atmospheric muons with the CMS detector
(Elsevier, 2010-07)
We present a measurement of the ratio of positive to negative muon fluxes from cosmic ray interactions in the atmosphere, using data collected by the CMS detector both at ground level and in the underground experimental ...
Measurement of the Ratio B ( B[subscript s][superscript 0] → J/ψf[subscript 0] (980))/B(B[subscript s][superscript 0] → J/ψϕ(1020)) in Pp Collisions at √s = 7 TeV
(Elsevier BV, 2016-02)
A measurement of the ratio of the branching fractions of the B[subscript s][superscript 0] meson to J/ψf0(980) and to J/ψφ(1020) is presented. The J/ψ, f[subscript 0](980), and φ(1020) are observed through their decays to ...
Measurement of inclusive jet production and nuclear modifications in pPb collisions at √SNN = 5.02 TeV
(Springer Berlin Heidelberg, 2016-07)
Inclusive jet production in pPb collisions at a nucleon–nucleon (NN) center-of-mass energy of √sNN = 5.02 TeV is studied with the CMS detector at the LHC. A data sample corresponding to an integrated luminosity of 30.1 ...
