Study of J/ψ meson production inside jets in pp collisions at s=8TeV
(Physics Letters B, 2020)
A study of the production of prompt J/ψ mesons contained in jets in proton-proton collisions at s=8TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 fb$^{−1}$ collected with ...
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=13TeV
(Physics Letters B, 2020)
The fiducial cross section for Y(1S) pair production in proton-proton collisions at a center-of-mass energy of 13 TeV in the region where both Y(1S) mesons have an absolute rapidity below 2.0 is measured to be 79±11(stat ...
Search for disappearing tracks in proton-proton collisions at s=13TeV
(Physics Letters B, 2020)
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 ...
Measurement of the CP-violating phase ϕs in the Bs 0→J/ψϕ(1020)→μ+μ−K+K− channel in proton-proton collisions at s=13TeV
(Physics Letters B, 2021)
The CP -violating weak phase ϕs and the decay width difference ΔΓs between the light and heavy Bs0 mass eigenstates are measured with the CMS detector at the LHC in a sample of 48500reconstructed Bs0→J/ψϕ(1020)→μ+μ−K+K− ...
Measurements of production cross sections of polarized same-sign W boson pairs in association with two jets in proton-proton collisions at s=13 TeV
(Physics Letters B, 2020)
The first measurements of production cross sections of polarized same-sign W±W± boson pairs in proton-proton collisions are reported. The measurements are based on a data sample collected with the CMS detector at the LHC ...
Measurement of CKM matrix elements in single top quark -channel Production in Proton-proton Collisions at
(Physics Letters B, 2020)
The first direct, model-independent measurement is presented of the modulus of the Cabibbo–Kobayashi–Maskawa (CKM) matrix elements |η|Vtb, |η|Vtd, and |η|Vts, in final states enriched in single top quark t-channel events. ...
Evidence for electroweak production of four charged leptons and two jets in proton-proton collisions at s=13TeV
(Physics Letters B, 2020)
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 ...
Measurement of the tt-bb- production cross section in the all-jet final state in pp collisions at √s=13 TeV

A measurement of the production cross section of top quark pairs in association with two b jets (tt‾bb‾) is presented using data collected in proton-proton collisions at s=13 TeV by the CMS detector at the LHC corresponding ...
Studies of charm and beauty hadron long-range correlations in pp and pPb collisions at LHC energies
(Physics Letters B, 2021)
Measurements of the second Fourier harmonic coefficient (v2) of the azimuthal distributions of prompt and nonprompt D$^{0}$ mesons produced in pp and pPb collisions are presented. Nonprompt D$^{0}$ mesons come from beauty ...
Search for dijet resonances using events with three jets in proton-proton collisions at s=13TeV
(Physics Letters B, 2020)
A search for a narrow resonance with a mass between 350 and 700 GeV, and decaying into a pair of jets, is performed using proton-proton collision events containing at least three jets. The data sample corresponds to an ...
