Search for pair-produced vectorlike B quarks in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2016-06)
A search for the production of a heavy B quark, having electric charge −13 and vector couplings to W, Z, and H bosons, is carried out using proton-proton collision data recorded at the CERN LHC by the CMS experiment, ...
Measurement of b hadron lifetimes in pp collisions at √s = 8 TeV
(Springer Berlin Heidelberg, 2018-06)
Measurements are presented of the lifetimes of the B[superscript 0], B[superscript 0][subscript s], Λ[superscript 0][subscript b], and B[superscript +][superscript c] hadrons using the decay channels B[superscript ...
Search for long-lived particles that decay into final states containing two electrons or two muons in proton-proton collisions at √s = 8 TeV
(American Physical Society, 2015-03)
A search is performed for long-lived particles that decay into final states that include a pair of electrons or a pair of muons. The experimental signature is a distinctive topology consisting of a pair of charged leptons ...
Measurement of the underlying event activity using charged-particle jets in proton-proton collisions at √s = 2.76 TeV
(Springer-Verlag/SISSA, 2015-09)
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[superscript jet]| < 2) and with transverse ...
Evidence for collectivity in pp collisions at the LHC
(Elsevier BV, 2017-02)
Measurements of two- and multi-particle angular correlations in pp collisions at √s=5, 7, and 13 TeV are presented as a function of charged-particle multiplicity. The data, corresponding to integrated luminosities of ...
Suppression and azimuthal anisotropy of prompt and nonprompt J/ψ production in PbPb collisions at √s[subscript NN] =2.76 TeV
(Springer Nature, 2017-04)
The nuclear modification factor R[subscript AA] and the azimuthal anisotropy coefficient v[subscript 2] of prompt and nonprompt (i.e. those from decays of b hadrons) J/ψ mesons, measured from PbPb and pp collisions at ...
A search for new phenomena in pp collisions at √s = 13 TEV in final states with missing transverse momentum and at least one jet using the α[subscript T] variable
(2017-05)
A search for new phenomena is performed in final states containing one or more jets and an imbalance in transverse momentum in pp collisions at a centre-of-mass energy of 13TeV. The analysed data sample, recorded with the ...
Search for same-sign top-quark pair production at √ s = 7 TeV and limits on flavour changing neutral currents in the top sector
(Springer Science and Business Media LLC, 2011)
An inclusive search for same-sign top-quark pair production in pp collisions at √s = 7TeV is performed using a data sample recorded with the CMS detector in 2010, corresponding to an integrated luminosity of 35 pb -1. This ...
Observation of Z decays to four leptons with the CMS detector at the LHC
(Springer Science and Business Media LLC, 2012)
The first observation of the Z boson decaying to four leptons in proton-proton collisions is presented. The analyzed data set corresponds to an integrated luminosity of 5.02 fb-1 at s=7 TeV collected by the CMS detector ...
Combined search for electroweak production of charginos and neutralinos in proton-proton collisions at √s = 13 TeV
(Springer International Publishing AG, 2018-03)
A statistical combination of several searches for the electroweak production of charginos and neutralinos is presented. All searches use proton-proton collision data at √s = 13 TeV, recorded with the CMS detector at the ...
