Evidence for X(3872) in Pb-Pb collisions and studies of its prompt production at √s NN = 5.02 TeV
(American Physical Society, 2022-01-19)
The first evidence for X(3872) production in relativistic heavy ion collisions is reported. The X(3872) production is studied in lead-lead (Pb-Pb) collisions at a center-of-mass energy of

Measurement of the inclusive and differential WZ production cross sections, polarization angles, and triple gauge couplings in pp collisions at s√ = 13 TeV
(Springer, 2022-07)
The associated production of a W and a Z boson is studied in final states with multiple leptons produced in proton-proton (pp) collisions at a centre-of-mass energy of 13 TeV using 137 fb−1 of data collected with the CMS ...
Study of quark and gluon jet substructure in Z+jet and dijet events from pp collisions
(Springer, 2022-01-31)
Measurements of jet substructure describing the composition of quark- and gluon-initiated jets are presented. Proton-proton (pp) collision data at s = 13 TeV collected with the CMS detector are used, corresponding to an ...
Strategies and performance of the CMS silicon tracker alignment during LHC Run 2
(Elsevier, 2022-08-11)
The strategies for and the performance of the CMS silicon tracking system alignment during the 2015–2018 data-taking period of the LHC are described. The alignment procedures during and after data taking are explained. ...
Measurement of double-parton scattering in inclusive production of four jets with low transverse momentum in proton-proton collisions at s√ = 13 TeV
(Springer, 2022-01-28)
A measurement of inclusive four-jet production in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The transverse momenta of jets within |η| < 4.7 are required to exceed 35, 30, 25, and 20 GeV ...
Evidence for WW/WZ vector boson scattering in the decay channel ℓνqq produced in association with two jets in proton-proton collisions at √s = 13 TeVeV
(Elsevier, 2022-11-10)
Evidence is reported for electroweak (EW) vector boson scattering in the decay channel ℓνqq of two weak vector bosons WV (V=W or Z), produced in association with two parton jets. The search uses a data set of proton-proton ...
Search for Wγ resonances in proton-proton collisions at √s = 13 TeV using hadronic decays of Lorentz-boosted W bosons
(Elsevier, 2022-03-10)
A search for Wγ resonances in the mass range between 0.7 and 6.0 TeV is presented. The W boson is reconstructed via its hadronic decays, with the final-state products forming a single large-radius jet, owing to a high ...
Search for flavor-changing neutral current interactions of the top quark and higgs boson in final states with two photons in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2022-07-13)
Proton-proton interactions resulting in final states with two photons are studied in a search for the signature of flavor-changing neutral current interactions of top quarks (t) and Higgs bosons (H). The analysis is based ...
Search for new particles in an extended Higgs sector with four b quarks in the final state at √s = 13 TeV
(Elsevier, 2022-12-10)
A search for a massive resonance X decaying to a pair of spin-0 bosons ϕ that themselves decay to pairs of bottom quarks, is presented. The analysis is restricted to the mass ranges mϕ from 25 to 100 GeV and mX from 1 to ...
Observation of the Bc+ meson in Pb-Pb and pp collisions at √s NN = 5.02 TeV and measurement of its nuclear modification factor
(American Physical Society, 2022-06-21)
The Bc+ meson is observed for the first time in heavy ion collisions. Data from the CMS detector are used to study the production of the Bc+ meson in lead-lead (Pb-Pb) and proton-proton (pp) collisions at a center-of-mass ...
