Calibration of the CMS hadron calorimeters using proton-proton collision data at √s = 13 TeV
(IOP Publishing, 2020-05)
Methods are presented for calibrating the hadron calorimeter system of theCMSetector at the LHC. The hadron calorimeters of the CMS experiment are sampling calorimeters of brass and scintillator, and are in the form of one ...
Multiparticle correlation studies in pPb collisions at √sNN = 8.16 TeV
(American Physical Society, 2020-01-23)
The second- and third-order azimuthal anisotropy Fourier harmonics of charged particles produced in pPb collisions, at root s(NN) = 8.16 TeV, are studied over a wide range of event multiplicities. Multiparticle correlations ...
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 ...
Search for new neutral Higgs bosons through the H→ZA→ℓ+ℓ−bb¯¯¯ process in pp collisions at s√ = 13 TeV
(Springer Nature, 2020-03-10)
This paper reports on a search for an extension to the scalar sector of the standard model, where a new CP-even (odd) boson decays to a Z boson and a lighter CP-odd (even) boson, and the latter further decays to a b quark ...
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 ...
Observation of the Λb 0→J/ψΛϕ decay in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-03-10)
The observation of the Lambda(0)(b) -> J/psi Lambda phi decay is reported using proton-proton collision data collected at root s = 13TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity ...
