Measurement of Bs 0 meson production in pp and PbPb collisions at sNN=5.02 TeV
(Elsevier, 2019-09-10)
The production cross sections of B-s(0) mesons and charge conjugates are measured in proton-proton (pp) and PbPb collisions via the exclusive decay channel B-s(0)-> J/ psi phi ->mu(+) mu(-) K+K- at a center-of-mass energy ...
Search for black holes and sphalerons in high-multiplicity final states in proton-proton collisions at s√=13 TeV
(Springer Nature, 2018-11)
A search in energetic, high-multiplicity final states for evidence of physics beyond the standard model, such as black holes, string balls, and electroweak sphalerons, is presented. The data sample corresponds to an ...
Search for vectorlike leptons in multilepton final states in proton-proton collisions at √ s = 13 TeV
(American Physical Society, 2019-09-06)
A search for vectorlike leptons in multilepton final states is presented. The data sample corresponds to an integrated luminosity of 77.4 fb(-1) of proton-proton collisions at a center-of-mass energy of 13 TeV collected ...
Study of the underlying event in top quark pair production in pp collisions at 13 TeV
(Springer Nature, 2019-02-07)
Measurements of normalized differential cross sections as functions of the multiplicity and kinematic variables of charged-particle tracks from the underlying event in top quark and antiquark pair production are presented. ...
Search for nonresonant Higgs boson pair production in the b b ¯ b b ¯ final state at √s = 13 TeV
(Springer Nature, 2019-04-17)
Results of a search for nonresonant production of Higgs boson pairs, with each Higgs boson decaying to a b (b) over bar pair, are presented. This search uses data from proton-proton collisions at a centre-of-mass energy ...
An embedding technique to determine ττ backgrounds in proton-proton collision data
(IOP Publishing, 2019-06)
An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau ...
Search for low-mass quark-antiquark resonances produced in association with a photon at √ s = 13 TeV
(American Physical Society, 2019-12-03)
A search for narrow low-mass resonances decaying to quark-antiquark pairs is presented. The search is based on proton-proton collision events collected at 13 TeV by the CMS detector at the CERN LHC. The data sample corresponds ...
Search for supersymmetry in events with a photon, jets, b-jets, and missing transverse momentum in proton–proton collisions at 13TeV
(Springer Nature, 2019-05-25)
A search for supersymmetry is presented based on events with at least one photon, jets, and large missing transverse momentum produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The data correspond ...
Search for physics beyond the standard model in events with jets and two same-sign or at least three charged leptons in proton-proton collisions at √s=13 TeV
(Springer Nature, 2020-08-18)
A data sample of events from proton-proton collisions with at least two jets, and two isolated same-sign or three or more charged leptons, is studied in a search for signatures of new physics phenomena. The data correspond ...
Measurement of the top quark polarization and t ¯ t spin correlations using dilepton final states in proton-proton collisions at √ s = 13 TeV
(American Physical Society, 2019-10-08)
Measurements of the top quark polarization and top quark pair (t¯t) spin correlations are presented using events containing two oppositely charged leptons (eþe−, eμ∓, or μþμ−) produced in proton-proton collisions at a ...
