Performance of the reconstruction and identification of high-momentum muons in proton-proton collisions at √s = 13 TeV
(IOP Publishing, 2020-02-28)
The CMS detector at the LHC has recorded events from proton-proton collisions, with muon momenta reaching up to 1.8 TeV in the collected dimuon samples. These high-momentum muons allow direct access to new regimes in physics ...
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 ...
Search for supersymmetry with a compressed mass spectrum in events with a soft τ lepton, a highly energetic jet, and large missing transverse momentum in proton-proton collisions at √ s = 13 TeV
(American Physical Society, 2020-01-29)
The first search for supersymmetry in events with an experimental signature of one soft, hadronically decaying tau lepton, one energetic jet from initial-state radiation, and large transverse momentum imbalance is presented. ...
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 ...
Measurement of quark- and gluon-like jet fractions using jet charge in PbPb and pp collisions at 5.02 TeV
(Springer Nature, 2020-07-17)
The momentum-weighted sum of the electric charges of particles inside a jet, known as jet charge, is sensitive to the electric charge of the particle initiating the parton shower. This paper presents jet charge distributions ...
Search for supersymmetry in proton-proton collisions at √s = 13 TeV in events with high-momentum Z bosons and missing transverse momentum
(Springer Nature, 2020-09-23)
A search for new physics in events with two highly Lorentz-boosted Z bosons and large missing transverse momentum is presented. The analyzed proton-proton collision data, corresponding to an integrated luminosity of 137 ...
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 ...
