Measurement of the single top quark and antiquark production cross sections in the tchannel and their ratio in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-01-10)
Measurements of the cross sections for the production of single top quarks and antiquarks in the t channel, and their ratio, are presented for proton-proton collisions at a center-of-mass energy of 13 TeV. The data set ...
Search for light pseudoscalar boson pairs produced from decays of the 125 GeV Higgs boson in final states with two muons and two nearby tracks in pp collisions at √s=13 TeV
(Elsevier, 2020-01-10)
A search is presented for pairs of light pseudoscalar bosons, in the mass range from 4 to 15 GeV, produced from decays of the 125 GeV Higgs boson. The decay modes considered are final states that arise when one of the ...
Measurement of CKM matrix elements in single top quark t-channel production in proton-proton collisions at √s = 13 TeV
(Elsevier, 2020-09)
The first direct, model-independent measurement is presented of the modulus of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements vertical bar V-tb vertical bar, vertical bar V-td vertical bar, and vertical bar V-ts ...
Observation of electroweak production of Wγwith two jets in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-12-10)
A first observation is presented for the electroweak production of a W boson, a photon, and two jets in proton-proton collisions. The W boson decays are selected by requiring one identified electron or muon and an imbalance ...
Search for disappearing tracks in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-07-10)
A search is presented for long-lived charged particles that decay within the volume of the silicon tracker of the CMS experiment. Such particles can produce events with an isolated track that is missing hits in the outermost ...
Evidence for WW production from double-parton interactions in proton–proton collisions at s√=13TeV
(Springer Nature, 2020-01-17)
A search forWWproduction from double-parton scattering processes using same-charge electron-muon and dimuon events is reported, based on proton-proton collision data collected at a center-of-mass energy of 13 TeV. The ...
Measurement of the Y(1S) pair production cross section and search for resonances decaying to Y(1S)μ+μ−in proton-proton collisions at √s=13 TeV
(Elsevier, 2020-09-10)
The fiducial cross section for Y(1S) pair production in proton-proton collisions at a center-of-mass energy of 13TeVin the region where both Y(1S) mesons have an absolute rapidity below 2.0 is measured to be 79 +/- 11 ...
Evidence for electroweak production of four charged leptons and two jets in proton-proton collisions at √s = 13 TeV
(Springer, 2021-01-10)
Evidence is presented for the electroweak (EW) production of two jets (jj) in association with two Z bosons and constraints on anomalous quartic gauge couplings are set. The analysis is based on a data sample of proton-proton ...
Studies of charm and beauty hadron long-range correlations in pp and pPb collisions at LHC energies
(Elsevier, 2021-02-10)
Measurements of the second Fourier harmonic coefficient (v2) of the azimuthal distributions of prompt and nonprompt D0 mesons produced in pp and pPb collisions are presented. Nonprompt D0 mesons come from beauty hadron ...
Measurement of prompt D0 and D0 meson azimuthal anisotropy and search for strong electric fields in PbPb collisions at √sNN = 5.02 TeV
(Elsevier, 2021-05-10)
The strong Coulomb field created in ultrarelativistic heavy ion collisions is expected to produce a rapidity-dependent difference (Δv2) in the second Fourier coefficient of the azimuthal distribution (elliptic flow, v2) ...
