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 an excited lepton that decays via a contact interaction to a lepton and two jets in proton-proton collisions at √s = 13 TeV
(Springer Nature, 2020-05-12)
Results are presented from a search for events containing an excited lepton (electron or muon) produced in association with an ordinary lepton of the same flavor and decaying to a lepton and two hadronic jets. Both the ...
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 ...
Studies of charm quark diffusion inside jets using Pb-Pb and pp collisions at √sNN = 5.02 TeV
(American Physical Society, 2020-09-03)
The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with p(T)(jet) > 60 GeV/c and D-0 mesons with p(T)(D) > 4 GeV/c in lead-lead ...
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 αT variable
(Springer International Publishing, 2017)
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 13 TeVTeV . The analysed data sample, recorded ...
Performance of the CMS Level-1 trigger in proton-proton collisions at √s = 13 TeV
(2020-10)
At the start of Run 2 in 2015, the LHC delivered proton-proton collisions at a center-ofmass energy of 13 TeV. During Run 2 (years 2015-2018) the LHC eventually reached a luminosity of 2.1 x 10(34) cm(-2) s(-1), almost ...
