Observation of two excited B + c states and measurement of the B + c ( 2 S ) mass in p p collisions at √ s = 13 TeV
(American Physical Society, 2019-04-02)
Signals consistent with the B-c(+)(2S) and B-c*(+)(2S) states are observed in proton-proton collisions at root s = 13 TeV, in an event sample corresponding to an integrated luminosity of 143 fb(-1), collected by the CMS ...
Measurement of the top quark mass using single top quark events in proton-proton collisions at √s = 8 TeV
(Springer International Publishing, 2017)
A measurement of the top quark mass is reported in events containing a single top quark produced via the electroweak
t channel. The analysis is performed using data from proton-proton collisions collected with the CMS ...
Mechanical stability of the CMS strip tracker measured with a laser alignment system
(IOP Publishing, 2017-04-21)
The CMS tracker consists of 206 m2 of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from −25 to +25°C. The mechanical stability of tracker ...
Measurement of the semileptonic t t ¯ + γ production cross section in pp collisions at √s=8 TeV
(Springer International Publishing, 2017-10-02)
A measurement of the cross section for top quark-antiquark ( tt¯tt¯ ) pairs produced in association with a photon in proton-proton collisions at s√=8s=8 TeV is presented. The analysis uses data collected with the CMS ...
Study of jet quenching with Z + jet correlations in Pb-Pb and pp collisions at √sNN=5.02TeV
(American Physical Society, 2017-08-23)
The production of jets in association with Z bosons, reconstructed via the mu(+)mu(-) and e(+)e(-) decay channels, is studied in pp and, for the first time, in Pb-Pb collisions. Both data samples were collected by the CMS ...
Erratum 2: Search for dark matter and unparticles in events with a Z boson and missing transverse momentum in proton-proton collisions at s√=13 TeV
(Springer Nature, 2018-01)
In the original paper, figure 10 was incorrect. The correct figure is shown below. Additionally, the unparticle entries in table 3, as well as figure 4 and 5 were labelled with incorrect values of ΛU.
Measurement of charged particle spectra in minimum-bias events from proton–proton collisions at √s=13TeV
(Springer Nature, 2018-08-31)
Pseudorapidity, transverse momentum, and multiplicity distributions are measured in the pseudorapidity range | η| < 2.4 for charged particles with transverse momenta satisfying pT>0.5GeV in proton–proton collisions at a ...
Measurement of differential cross sections for Z boson pair production in association with jets at √s=8 and 13 TeV
(Elsevier, 2019-02-10)
This Letter reports measurements of differential cross sections for the production of two Z bosons in association with jets in proton-proton collisions at root s = 8 and 13 TeV. The analysis is based on data samples collected ...
Inclusive search for supersymmetry in pp collisions at s√ = 13 TeV using razor variables and boosted object identification in zero and one lepton final states
(Springer Nature, 2019-03-06)
An inclusive search for supersymmetry (SUSY) using the razor variables is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 35.9 fb(-1), collected with the CMS experiment ...
Search for anomalous triple gauge couplings in WW and WZ production in lepton + jet events in proton-proton collisions at s√ = 13 TeV
(Springer Nature, 2019-12-09)
A search is presented for three additional operators that would lead to anomalous WWγ or WWZ couplings with respect to those in the standard model. They are constrained by studying events with two vector bosons; a W boson ...
